Chemical Formula Determination Experiment Result

What is the empirical formula for the product in the experiment?

Based on the experiment data, what is the empirical formula for the product?

Answer:

The empirical formula for the product in the experiment is PbO.

In an experiment using lead and oxygen, the following data was gathered to determine the empirical formula for the product. The empirical formula is generally used to simply show what fundamentals are present in a patch. The empirical formula of the product is PbO. Given the data of the masses involved in the experiment and the calculations made, the molecular formula of the product is determined to be PbO.

The mass measurements conducted in the experiment are crucial in determining the empirical formula. By subtracting the mass of the evaporating dish and cover from the total mass of the evaporating dish, cover, and lead, we can find the mass of the converted lead. Similarly, by subtracting the mass of the evaporating dish and cover from the total mass of the evaporating dish, cover, and lead oxide product, we can find the mass of oxygen present in the product.

The mass of converted lead: 22.45 grams - 19.50 grams = 2.95 grams

Moles of lead: 2.95 g / 207.2 g/mol = 0.01 g/mol

Lead oxide mass: 22.90 grams - 19.50 grams = 3.4 grams

Oxygen present: 3.4 grams - 2.95 grams = 0.45 grams

Moles of oxygen: 0.45 g / 16 g/mol = 0.028 moles

Therefore, the empirical formula for the product in the experiment is PbO, where Pb represents lead and O represents oxygen.
