Question

Quizplus · Accepted Answer

CO has a molar mass of 28 g/mol, with one carbon atom (12 g/mol) and one oxygen atom (16 g/mol). Therefore, 1 g of CO contains 0.429 g of carbon (12/28). CO₂ has a molar mass of 60.06 g/mol, with one carbon atom (12 g/mol), one oxygen atom (16 g/mol), and one sulfur atom (32.06 g/mol). Therefore, 1 g of CO₂ contains 0.199 g of carbon (12/60.06). Thus, 1 g of CO contains more mass of carbon than 1 g of CO₂.
