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 2 moles of oxygen atoms, so there are 2 * 1.183 = 2.366 moles of oxygen atoms. Using Avogadro's number (6.022 × 10^23 atoms/mol), the number of oxygen atoms is 2.366 * 6.022 × 10^23 = 1.424 × 10^24.
