Carbon tetrachloride has a chlorine-to-carbon mass ratio of 11.8:1. if a sample of carbon tetrachloride contains 27 g of chlorine, what mass of carbon does it contain?
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
