Question

Quizplus · Accepted Answer

The molar mass of CO2 is 44.01 g/mol. 52.06 g of CO2 is 52.06/44.01 = 1.183 moles. Each mole of CO2 contains Avogadro's number (6.022 × 10^23) of molecules, and each molecule contains one carbon atom. Therefore, the number of carbon atoms is 1.183 × 6.022 × 10^23 = 7.122 × 10^23.
