Chemistry question about dicyclohexyl?

Question

The ratio of carbon atoms to hydrogen atoms to oxygen atoms in a molecule of dicyclohexyl maleate is 4 to 6 to 1. What is its molecular formula if its molar mass is 280 g?

Answer 1

Molar masses of elements x number of ratio:

4 (12.012) + 6 (1.007) + 1 (15.999)= 70.0894

280/70.0894 = 3.99 ->4

Multiply all ratios by 4 to get the molecular formula.

So:

The formula is: H24C16O4
