Calculate the molar mass of the following

The molar mass of a compound is calculated by adding the atomic masses (in g/mol or amu) of the constituent atoms.

Molar masses of given compounds can be calculated as:

H₂0

Atomic mass of H = 1amu

Atomic mass of O = 16 amu

Hence, Molar mass of H20 = (2 x 1) + 16 = 18 g/mol

CO₂

Atomic mass of C = 12amu

Atomic mass of O = 16 amu

Hence, Molar mass of CO2 = 12 + (16 x 2) = 44 g/mol

CH₄

Atomic mass of C = 12amu

Atomic mass of H = 4 amu

Hence, Molar mass of CH4 = 12 + (1 x 4) = 16 g/mol

Final Answer:

The molar masses are:

1. 18 g/mol
2.  44 g/mol
3.  16 g/mol
