    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%
