|
Answer» Molar mass CO2 = 44 g/molYou have 4.4g , so you have 4.4/44 = 0.1 mol CO21mol CO2 has 6.022*10^23 molecules0.1mol CO2 has (6.022*10^23)*0.1 = 6.022*10^22 molecules1molecule of CO2 contains 2 atoms of OTherefore, 6.022*10^22 molecules of CO2 will contain (6.022*10^22) *2 = 1.204*10^23 atoms O |
