a.
3.52g CO2 x (atomic mass C/molar mass CO2) = g C.
1.44 g H2O x (2*atomic mass H/molar mass H2O) = g H.
g O = 2.4 - gC - g H
b. Can you finish? If you need more assistance please post your work and explain what you don't understand in detail.
2.4g of a compound of carbon, hydrogen and oxygen gave on combustion, 3.52g of CO2 and 1.44g of H2O. The relative molecular mass of the compound was found to be 60.
a)What are the masses of carbon, hydrogen and oxygen in 2.4g of the compound?
b)What are the emperical and molecular formulae of the compound?
