    Answer: 0.77 mole

    Explanation:

    Atomic mass of Ca = 40g/mol

    Atomic mass of O = 16g/mol

    Atomic mass of H = 1

    Therefore,

    1 mole of Ca (OH) _2 contains

    40+[16+1]2

    = 40+34

    =74g/mole

    Hence,

    1 mole of Ca (OH) _2 = 74g

    Let x mole of Ca (OH) _2 = 56. 78

    x = 56.78/74

    x = 0.77 mole
