What volume of chlorine is required to obtain 6 g of chloromethane?

We get chloromethane: Cl2 + CH4 = CH3Cl + HCl.
Knowing the mass of chloromethane, we can calculate its amount of substance. To do this, you need to calculate the molar mass of the substance and then find its amount.
12 + 3 + 35.5 = 50.5.
6 / 50.5 = 0.12 mol is the amount of chloromethane substance.
One mole of chloromethane accounts for one mole of chlorine. This means that the amount of chlorine is 0.12 mol.
The volume of chlorine is found by multiplying its amount of substance by the molar volume: 0.12 * 22.4 = 2.688 liters – the answer.
