A compound is formed by 24 g of X and 64 g of oxygen. If atomic mass of X = 12 and O = 16, calculate the simplest formula for the compound.
mass of oxygen = 64g.
Atomic mass of oxygen given as 16. Thus, atoms of oxygen = = 4.
mass of X = 24g.
Atomic mass of X given as 12. X is therefore carbon. Number of carbon atoms = = 2.
The ratio between them is 2: 4 = 1: 2
The simplest atomic formula is, therefore, CO2
