given :
5g of A reacts with 6g B
⇒ C and D are formed where C is 4g
need to find out :
the weight of D
solution :
according to the law of conservation of mass -
⇒ mass of products = mass of reactants of chemical reaction
mass of reactants = 5g + 6g
= 11g
let the weight of D be X
⇒ 4g + X = 11g
⇒ X = 11g - 4g
⇒ X = 7g
∴ the weight of D = 7g
