Question

Grams of solute needed

Answer 1

grams of solute = 31.5 g

Step-by-step explanation:

Given data:

Grams of solute = ?

%m/v = 3%

Volume = 1050 mL

Solution:

grams of solute = 3 g of NH₄Cl / 100 mL × 1050 mL

grams of solute = 0.03 g × 1050

grams of solute = 31.5 g

So 31.5 g are needed to to make 3% m/v solution.
