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.
