Find the compound’s empirical and molecular formula given that is M r is 180: We assume that we’ve got 100g of this carbohydrate. Then we have 40g of carbon and 6.66g of hydrogen, we can now find oxygen’s mass and the number of moles we have of each element, thus we can get the simplest ratio between them and get the empirical formula.

The ratio of the moles of each element will provide the ratio of the atoms of each element. Convert the mass of each element to moles of each element using the atomic masses. Find the ratio of the moles of each element by dividing the number of moles of each by the smallest number of moles. Use the mole ratio to write the empirical formula.
