Calculate the mass of 0.72 grams molecule of carbon dioxide
Molar mass of CO2 is (12+ 16*2) = 44 g/mol.
1 gram molecule of CO2 =44g
0.72gram molecule of CO2=(44g)/(1g)×(0.72g)=31.68g
3 grams of carbon is burnt completely in 8 gram of Oxygen and 11 gram of carbon dioxide is produced the mass of carbon dioxide formed when 9 gram of carbon burns in 50 gram of oxygen is
