    Explanation:

    Molarity of NaOH = 0.75 M

    Density of solution = 1.1 g/mL

    Mass percent of NaOH = ?

    Solution:

    Number of moles of NaOH = 0.75 mol from 0.75 mol/L

    Mass of NaOH = number of moles * molar mass

    Mass of NaOH = 0.75 mol * 40 g/mol

    Mass of NaOH = 30 g

    Mass of solution:

    d = m/v

    1.1 g / mL = m / 1000 mL

    m = 1100 g

    Percentage of NaOH:

    % NaOH = mass of solute / mass of solution * 100

    % NaOH = 30 g / 1100 g * 100

    % NaOH = 2.73%
