We’re being asked to determine the empirical formula of a compound that contains 2.64 g of C, 0.444 g of H, and 3.52 g of O.
Recall that the empirical formula is the simplest whole-number ratio formula of a compound.
This means we need to do the following steps:
Step 1: Calculate the moles of C, H, and O in the compound.
Step 2: Determine the lowest whole number ratio of C, H, and O to get the empirical formula.
Now, we need to get the moles of each element in the compound. The atomic masses are 12 g/mol C, 1 g/mol H, 16 g/mol O.
What is the empirical formula of a substance that contains 2.64 g of C, 0.444 g of H, and 3.52 g of O?
