Using rounded atomic masses (C=12, H=1, O=16), what is the molar mass of methanol (CH4O)?

By /

A) 32 g/mol

B) 48 g/mol

C) 16 g/mol

D) 33 g/mol

Answer: A

Explanation: Molar mass is the sum of atomic masses multiplied by the number of each atom. For CH4O, add 1×12 + 4×1 + 1×16 to obtain 32 g/mol.
