    Calculate the molecular mass of CH₃OH. (Atomic mass C-12, H-1, O-16)
    Question

    Calculate the molecular mass of CH₃OH.
    (Atomic mass C-12, H-1, O-16)

    A.

    32 g

    B.

    31 g

    C.

    30 g

    D.

    35 g

    Correct option is A


    The molecular mass of CH₃OH is calculated by adding the atomic masses of its constituent atoms:
    Carbon (C): 1 atom × 12 = 12
    Hydrogen (H): 4 atoms × 1 = 4
    Oxygen (O): 1 atom × 16 = 16
    Total molecular mass = 12 + 4 + 16 = 32 g
    Therefore, the correct answer is (a) 32 g.
