Lab 2 - Determination of the Empirical Formula of Magnesium Oxide

 

empirical formula lab report

The formula for a compound is an abbreviation used to indicate the elemental composition and relative numbers of atoms in the compound. The formula may be an empirical formula (also called a simple formula) or a molecular formula. An empirical formula gives the simplest whole number ratio of atoms of each element in a compound. Chemistry Lab Report-Determining the Empirical Formula of a compound. Ellen Liu. Ellen Liu IBDP-1 Chemistry HL 16/11/03 Title: Determining the Empirical Formula of a compound Material Needed: 1 crucible and cover 1 support stand and ring 1 crucible tong 1 clay triangle 1 electronic balance 1 alchole burner, ignition source 1 asbestos gauze. Number of empirical units = ( g/mol) / ( g/mol) = 6 empirical units Multiplying the empirical formula by 6 gives the molecular formula of benzene, (CH) X 6 or C 6 H 6. Experimentally, we can determine the empirical formula of a compound by first finding the mass of each element in a sample of the compound. We then convert the mass of.


Magnesium Oxide Lab Report | Magnesium | Oxygen


Lee Days of class: Tuesday and Thursday Time of class: 6. The objective of this experiment is to determine the ratio of the element, Mg, in a compound, based on the law of definite composition: Each compound is characterized by constant and definite composition. We determine the empirical formula of magnesium oxide that if formed when it reacts with oxygen gas. According to this law, the total mass of the products of a chemical reaction must equal the total mass of the reactants.

Therefore, the ratio between the number of moles of magnesium used and the number of moles of oxygen consumed empirical formula lab report then be calculated and the empirical formula lab report formula of magnesium oxide can be written on the basis of this ration.

Crucible and cover, tongs, wire gauze, ring stand, iron ring, clay triangle, gas burner, analytical balance. Record the mass. Repeat the procedure of opening- closing empirical formula lab report several times during the period about 10 minutes of heating.

Careful not to ignite the magnesium with the flame. Mass of the empty crucible and lid Mass of the crucible, lid, and Mass of the metal 0.

Mass of the metal Oxide 0. Mass of the oxygen 0. Mass of the metal oxide 0. Moles of metal 0. Moles of Oxygen 5. Ratio Mass of the crucible, empirical formula lab report, lid, and metal before heating :. Finally, we needed: 0. This empirical formula lab report came from because we take in count the magnesium react completely. Report No 5 Determination of Empirical Formula. This experiment demonstrates the technique used to determine the simple mole ratio of the elements in a compound.

Magnesium metal will be made to react with oxygen of the air to produce a binary compound, magnesium oxide, empirical formula lab report. The magnesium bums by heating with a very hot flame. Under high temperatures the magnesium also combines with the atmospheric nitrogen to produce magnesium nitride, which is not the desired product for this experiment. This compound can be converted to the desired product, magnesium oxide, by adding a few drops of water to the burned reaction mixture, then heating the mixture again.

The excess water is removed by evaporation during the heating step. Crucible and cover, tongs, wire gauze, ring stand, iron ring, clay triangle, gas burner, balance [Draw a sketch of the apparatus setup]. Heat them with a strong flame two-cone flame with inner blue cone for 8 to 10 minutes.

Weigh the crucible and the lid carefully using an analytical balance, empirical formula lab report, and record the inass. Determine the mass of magnesium. Weigh and record the mass of the crucible, lid and Mg, using the same analytical balance. Use a crucible tong to open the lid slightly, then close it in order for the oxygen to come in contact with the metal. Repeat the procedure of opening-closing lid several times during the period about 10 minutes of heating.

Open the lid and add a few drops of Empirical formula lab report about 3 or 4 drops to react with magnesium nitride. Heat the crucible again with the lid slightly open for 2 minutes with gentle heating, followed by 10 minutes of very strong heating. Divide your answers in 10 and 11 with the smallest answer, and report the mole ratio as. Ask your instructor for the true formula weight of the compound, then determine the formula of this metal oxide.

Introduction The objective of this experiment is to determine the ratio of the element, Mg, in a compound, based on the law of definite composition: Each compound is empirical formula lab report by constant and definite composition. Material Crucible and cover, tongs, wire gauze, ring stand, iron ring, clay triangle, gas burner, analytical balance. Procedure 3, empirical formula lab report.

Data: 1. Report No 5 Determination of Empirical Formula Experiment 6: Determination of Empirical Formula This experiment demonstrates the technique used to determine the simple mole ratio of the elements in a compound. Clean a porcelain crucible and its lid. Rinse them with distilled water. Turn off the flame and let the crucible cool down to room temperature.

Obtain a strip of the magnesium metal approximately 7 to 10 cm long. Roll the magnesium strip into a loose ball 3. Place it in the crucible. Heat the cnicible empirical formula lab report the lid completely covering its top. The heating must be gentle at first about 5 minutes with a weak flame.

After 5 minutes, increase to a strong two-cone blue flame. Remove the flame and close the lid, and let the crucible cool down. Weigh the crucible and empirical formula lab report, and record the mass.
