x g of propane (C3H8) on combustion with 32 g of oxygen produces 26.4 g of CO2 and 14.4 g of H2O. The value of x is:
7.5 g
6.3 g
4.9
8.8 g
C3H8 + 5O2 → 3CO2 + 4H2O
x g 32 g 26.4 g 14.4 g
According to law of conservation of mass "mass is neither created nor destroyed during a chemical change"
Mass of the reactants = Mass of products
x + 32 = 26.4 + 14.4 x = 8.8 g
