Computing Molar Mass of Bromooctane Step by Step

Molar Mass of Bromooctane: Step-by-Step Calculation

1. Identify Element Counts

Read C8H17Br and list how many atoms of each element are present:

  1. 8 atoms of Carbon (C)
  2. 17 atoms of Hydrogen (H)
  3. 1 atom of Bromine (Br)

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. Bromine (Br) ~= 79.904 g/mol

3. Multiply Atomic Mass by Quantity

Multiply atom count by atomic mass for each element:

  • Carbon (C): 8 x 12.011 = 96.090 g/mol
  • Hydrogen (H): 17 x 1.008 = 17.140 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 = (8 x 12.011 + 17 x 1.008 + 1 x 79.904)

Molar Mass = 96.090 + 17.140 + 79.900

Molar Mass = 193.130 g/mol

Final rounded value shown on this page: 193.13 g/mol.
