  • The number of grams present in 0.54 moles of calcium is; 22 g

    We are given;

    Number of moles; n = 0.54 moles

    Now, Molar mass of calcium is;

    M = 40.1 g

    Formula for number of moles is;

    n = m/M

    Where;

    n is number of moles

    m is mass in grams

    M is molar mass

    Thus;

    0.54 = m/40.1

    m = 40.1 × 0.54

    m = 21.654 g

    Approximately m = 22 g
