Computing Molar Mass of CH4 Step by Step
Molar Mass of CH4: Step-by-Step Calculation
1. Identify Element Counts
Read CH4 and list how many atoms of each element are present:
- 1 atom of Carbon (C)
- 4 atoms of Hydrogen (H)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Carbon (C) ~= 12.011 g/mol
- Hydrogen (H) ~= 1.008 g/mol
3. Multiply Atomic Mass by Quantity
Multiply atom count by atomic mass for each element:
- Carbon (C): 1 x 12.011 = 12.010 g/mol
- Hydrogen (H): 4 x 1.008 = 4.030 g/mol
4. Sum Total Molar Mass
Add all contributions to get the final molar mass in g/mol.
Molar Mass = (1 x 12.011 + 4 x 1.008)
Molar Mass = 12.010 + 4.030
Molar Mass = 16.040 g/mol
Final rounded value shown on this page: 16.04 g/mol.
