Answer:
according to law of conservation of mass
equation must be balanced. total mass of reactant must be equal to the total mass of product. therefore mass of a is equal to......
mass of reactants = x + 4.5
mass of products = 6 + 1.2 = 7.2
according to law of conservation of mass
x + 4.5 = 7.2
x = 7.2 - 4.5= 2.7
hence, mass of a is equal to 2.7 which would be decomposed by 4.5 g of b.
