a) 4.9 g

Let the mass of the answer be x g.

{Share by mass} = {{mass of solute}}{ {mass of solvent}} instances 100

Substitute values within the above expression.

35={1.7 g NH4Cl}{x } x 100

Therefore, x=4.9 g

Therefore, the mass of the answer is 4.9 g.

Thus, the choice A is the right reply

(1.7 g) / (0.35) = 4.9 g

X * 0.35 = 1.7 g

Crunch the numbers.
