Computing Molar Mass of Bromomethane Step by Step
Molar Mass of Bromomethane: Step-by-Step Calculation
1. Identify Element Counts
Read C1H3Br and list how many atoms of each element are present:
- 1 atom of Carbon (C)
- 3 atoms of Hydrogen (H)
- 1 atom of Bromine (Br)
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
- Bromine (Br) ~= 79.904 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): 3 x 1.008 = 3.020 g/mol
- Bromine (Br): 1 x 79.904 = 79.900 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 + 3 x 1.008 + 1 x 79.904)
Molar Mass = 12.010 + 3.020 + 79.900
Molar Mass = 94.940 g/mol
Final rounded value shown on this page: 94.94 g/mol.
