Question

If law of conservation of mass was to hold true, then 1.70 g of AgNO, on reacting with 0.365 g of
HCI will produce 1.435 g of AgCl and HNO3 equal to :
(A) 6.33 g
(B) 0.63 g
(C) 63.3 g
(D) 60.3 g​

Answer 1

Answer:

0.63 g

Explanation:

as you know that law of comservation of mass is that the sum of masses of reactants is equal to sum of masses of products so here :

let us consider mass of HNO3 as X

mass of (AgNO3 + HCl) = mass of (AgCl + HNO3)

1.70 g + 0.365 g = 1.435 + X

2.065 = 1.435+ X

2.065 -1.435 = X

0.63 = X

so mass of HNO3 produced will be 0.63g
