    First of all we need no. of moles of 100g sodium chromate

    Molar mass of sodium chromate = 161.97g/mol

    No of mole = mass in gram/molar

    =100/161.97

    = 0.617mol

    Now to find molarity apply formula

    Molarity = moles of solvent/solution in liter

    = 0.617/5

    =0.1234M solution of sodium chromate
