Quizplus · Accepted Answer

To find the mass of 3.06 x 10^23 molecules of CO₂, we need to first determine the molecular weight of CO₂. C = 1 x 12.01 = 12.01 O = 1 x 15.99 = 15.99 S = 1 x 32.07 = 32.07 Molecular weight of CO₂ = 12.01 + 15.99 + 32.07 = 60.07 g/mol Now we can calculate the mass of 3.06 x 10^23 molecules: Mass = (3.06 x 10^23 molecules) x (60.07 g/mol) = 1.837 x 10^25 g Mass in grams (g) = 18370000000000000000000000 g The only answer choice that is close to this value is B, 2.24g. Therefore, the best answer choice is B.
