MCQ

Problem:

3 g of a hydrocarbon on combustion with 11.2 g of oxygen produces 8.8 g of CO2 and 5.4 g of H2O.The data illustrates the law of
(a) Conservation of mass
(b) Multiple proportions
(c) Definite proportions
(d) Avogadros law


Solution:

Masses of hydrocarbon and oxygen = 3 g + 11.2 g = 14.2 g
Masses of CO2 and H2O = 8.8 g + 5.4 g = 14.2 g
Masses of reactants = masses of products
So, law of conservation of mass is illustrated. Correct option is (a).
