Question

A solution is made containing 22.8 g of magnesium nitrate per 325 g of water. What is the weight/ weight % or percent by mass of the solute?

Answer 1

6.56%

Step-by-step explanation:

mass of solute = 22.8 g

mass of solution = mass (solute) + mass (water) = 22.8 + 325 = 347.8 g

% by mass = [mass(solute)/ mass(solution)]*100% =(22.8/347.8)*100% = 6.56%
