Question

Determine the empirical formula of a compound containing 40.6 grams of carbon, 5.1 grams of hydrogen, and 54.2 grams of oxygen.

In an experiment, the molar mass of the compound was determined to be 118.084 g/mol. What is the molecular formula of the compound?

For both questions, show your work or explain how you determined the formulas by giving specific values used in calculations.

Answer 1

Calculating the empirical formula is a long process

We have Carbon (40.6g), Hydrogen (5.1g), and Oxygen (54.2g)

First, you'll need to find the moles for each element. Do you know how to find that?

Answer 2

You'll need the molar mass of each element, are you aware of what this is?

Answer 3

Great, do you know what the molar mass of either elements (carbon, hydrogen or oxygen) are?
