Computing Molar Mass of Propene Step by Step

Molar Mass of Propene: Step-by-Step Calculation

1. Identify Element Counts

Read C3H6 and list how many atoms of each element are present:

  1. 3 atoms of Carbon (C)
  2. 6 atoms of Hydrogen (H)

2. Determine Atomic Masses

Look up each element mass from the periodic table:

  1. Carbon (C) ~= 12.011 g/mol
  2. Hydrogen (H) ~= 1.008 g/mol

3. Multiply Atomic Mass by Quantity

Multiply atom count by atomic mass for each element:

  • Carbon (C): 3 x 12.011 = 36.030 g/mol
  • Hydrogen (H): 6 x 1.008 = 6.050 g/mol

4. Sum Total Molar Mass

Add all contributions to get the final molar mass in g/mol.

Molar Mass = (3 x 12.011 + 6 x 1.008)

Molar Mass = 36.030 + 6.050

Molar Mass = 42.080 g/mol

Final rounded value shown on this page: 42.08 g/mol.
