Answer:

5.89%

Explanation:

We are given;

  • Mass of the solute, LiOH as 40.1 g
  • Mass of the solvent, H₂O as 681 g

We are required to calculate the mass percent composition of solution;

  • But; How do we calculate the mass percent composition of a solution?
  • We use the formula;
  • Mass composition of a solution = (Mass of solute/mass of solution) 100%
  • Therefore;

Mass Percent = (40.1 g/681 g)× 100%

                       = 5.888 %

                       = 5.89%

Therefore, the mass percent composition of the solution is 5.89%
