    Explanation:

    To calculate the percentage of carbon in BeC2O4•3H2O, first we calculate the molar mass of BeC2O4•3H2O

    MM of BeC2O4•3H2O = 9 + (12x2) + (4x16) + 3 (2+16) = 9+24+64+54 = 151g/mol

    Mass of C in BeC2O4•3H2O = 2x12 = 24g

    %Mass of carbon in BeC2O4•3H2O = (24/151) x 100

    = 15.89%
