How many grams of Cl are in 38.3 g of CHCl3?

From the periodic table:

mass of H = 1 gram

mass of C = 12 grams

mass of Cl = 35.5 grams

Therefore,

mass of CHCl3 = 12+1+3 (35.5) = 119.5 grams

3Cl = 3 (35.5) = 106.5 grams

This means that each 119.5 grams of CHCl3 contains 106.5 grams of Cl. To know the mass of Cl present in 38.3 grams of CHCl3, all you have to do is cross multiplication as follows:

mass of Cl = (38.3*106.5) / (119.5) = 34.1334 grams
