Question

You have prepared calcium oxide in the lab. While you were conducting your experiment, you recorded that you had 0.045 g of calcium and 0.035 g of oxygen. a) Based on your data, what is the empirical formula for calcium oxide? Show your work. b) Did your experiment lead to an accurate conclusion? If not, explain how you determined that your empirical formula was not accurate.

Step 1

First, we need to find the moles of each element in the compound. Moles of calcium (Ca) = mass / molar mass Moles of calcium = 0.045 g / 40.08 g/mol = 0.00112 mol Moles of oxygen (O) = mass / molar mass Moles of oxygen = 0.035 g / 16.00 g/mol = Show more…
