    Answer: 138g/mol


    K2CO3 is the chemical formula for potassium trioxocarbonate

    For molar mass of K2CO3, use the molar masses:

    Potassium, K = 39g;

    Carbon, C = 12g;

    Oxygen, O = 16g

    K2CO3 = [ (39g x 2) + 12g + (16g x 3) ]

    = 78g + 12g + 48g

    = 138g/mol

    Thus, the molar mass of K2CO3 is 138g/mol
