Number of molecules = 6.02 X 1023 molecules
We know that
6.02 X 1023 molecules equals 1 mole.
Mass of CO2
No of moles = Given mass/molar mass
The molar mass of CO2 is 44 gram/mol.
Mass of CO2= no of moles × molar mass
Substituting the values in the formula we get
Mass of CO2 = 1 mol × 44
Mass of CO2 = 44 grams
Hence, Mass of CO2 = 44 grams
