moles calculations a level chem

How do I find the number of moles from this info, to then find the molar ratio:
1.30g zing combines with 0.24g of carbon and 0.96 of oxygen to give a compound of RMM 125.4

Divide all the masses you've been given by their relative atomic masses (which gives the amount in mol). Divide all three numbers you've just calculated by the smallest of those numbers, which will give the ratio of the three atoms, i.e. the empirical formula. I'll see if you can do the rest.
