Question

The chemical formula for propane is: CH3CH2CH3 Calculate the molar mass of propane. Round your answer to 2 decimal places.

Answer 1

Answer:

44.11 g/mol

Explanation:

In order to calculate the molar mass of any molecule, we need to add the molar mass of each atom that compounds it:

• Molar Mass of C₃H₈ = (Molar Mass of C) * 3 + (Molar Mass of H)*8

• Molar Mass of C₃H₈ = (12.01) * 3 + (1.01) * 8

• Molar Mass of C₃H₈ = 44.11 g/mol

The molar mass of propane is thus 44.11 g/mol.
