    dа ta:

    Molarity, M = 1.25 M

    mass, m = 36 grams

    Solute, H2SO4

    Formulas:

    M = n / V = > V = n / M

    n = mass in grams / molar mass

    Solution:

    molar mass of H2SO4 = 98.079 g/mol

    n = 38 g / 98,079 g/mol = 0.3874 mol

    V = 0.3874 mol / 1.25M = 0.31 liter

    Answer: 0.31 liter
