According to the law of conservation of mass, 3 g of carbon burnt in 8 g of oxygen forms 11 g of carbon dioxide. Now, what will be the mass of carbon dioxide produced when 3 g of carbon is burnt in 50 g of oxgyen?
53 g
Law of conversation of mass states that mass of carbon dioxide produced will be equal to (mass of carbon + mass of oxygen) i.e. 50 + 3 = 53 g.
