Jasmine Sullivan · Answer 1

The ratio of Cl to C is 11.8:1

The mass of Cl present in the compound is 11.8 times the mass of carbon present.

If there’s 11.8 g of Cl - mass of C is 1 g

If there’s 1 g of Cl - mass of C is 1/11.8

Therefore when there’s 27 g of chlorine - mass of C is 1/11.8 x 27 = 2.29 g

When there’s 27 g of chlorine then mass of C present is 2.29 g
