    (Na2CO3) x

    Explanation:

    Molar mass of Na = 23

    Molar mass of C = 12

    Molar mass of O = 16

    Divide by the molar mass

    Na C O

    43.3/23 11.3/12 45.4/16

    1.88 0.94 2.83

    Divide all through by the smallest number 0.94

    1.88/0.94 0.94/0.94 2.83/0.94

    2 1 3

    Na2CO3

    (Na2CO3) x
