Molecular mass of CH3 OH =

32g/mol

Explanation:

When dealing with a compound, the molar mass is the gram - formula mass or gram moleclular weight. This is determined by the addition of its component atomic masses.

For CH₃OH;

Atomic mass of C = 12g/mol , H  = 1g/mol, O  = 16g/mol

 So,

     Molecular mass  = 12 + 3(1)  + 16 + 1  = 32g/mol

your answer would be a. 12.5 kg

i believe the answer is a.
