    Answer: (A) 44.0 g/mol

    Explanation:

    Molar mass of a compound is the sum total of all the individual masses of the constituent elements present in the compound.

    Molar mass of C3H8 =

    C = 12.0 g/mol

    H = 1.00 g/mol

    Molar mass of C3H8 = (12*3) + (1*8) = 36 + 8 = 44 g/mol.

    Molar mass of C3H8 = 44g/mol

    C = 12 g/mol

    H = 1 g/mol

    C3H8

    C: 12 g/mol * 3 = 36 g/mol

    H: 1 g/mol * 8 = 8 g/mol

    36 + 8 = 44 g/mol

    Answer: A) 44.0 g
