Rachel Boyd · Answer 1

Atomic mass C = 12.0107

Atomic mass O = 15.9994

Calculate the molecular mass of the CO2

12.0107 + (2 x 15.9994) = 44.0095

Multiply the mass of CO2 by the conversion factor that relate the O mass to the molecular mass of CO2 to find the mass of O in the 71.89g of CO2

71.89 g CO2 x (2 x 15.9994) / 44.0095 =

52.2703900748702

52.27 g O
