How many grams of carbon are present in 45.0 g of CCl₄? A)0.293 g B)3.51 g C)5.76 g D)41.49 g

Question

Quizplus · Accepted Answer

In CCl₄, there is only one carbon atom present. The molar mass of this compound is 154.82 g/mol. Therefore, the mass percent of carbon in this compound is (12.01 g/mol / 154.82 g/mol) x 100% = 7.76%. To find the mass of carbon in 45.0 g of the compound, we can multiply the mass percent of carbon by the total mass of the compound: (7.76% x 45.0 g) / 100% = 3.49 g ≈ 3.51 g.
