Calculate the molecular masses of CH3OH.
(Atomic mass C-12,H-1,O-16)
-
A.
32 g
-
B.
31 g
-
C.
30 g
-
D.
35 g
Correct Answer:
A. 32 g
Explanation:
To find the molecular mass of methanol (CH3OH), you add the atomic masses of all the atoms in the molecule. The formula contains one carbon atom (12), four hydrogen atoms (4 x 1 = 4), and one oxygen atom (16). Summing these values (12 + 4 + 16) results in a total molecular mass of 32 g/mol.
