Molar mass of Isopropyl alcohol, C₃H₈O
60.096 g/mol
Molecular weight 60.096 · 12 atoms per formula unit
Also known as: c3h8o, isopropanol, rubbing alcohol.
Rubbing alcohol; a secondary alcohol, so it oxidises to a ketone rather than an acid.
How 60.096 g/mol is worked out
| Element | Atoms | Atomic mass | Mass | % of total |
|---|---|---|---|---|
| Carbon | 3 | 12.011 | 36.033 | 59.96% |
| Oxygen | 1 | 15.999 | 15.999 | 26.62% |
| Hydrogen | 8 | 1.008 | 8.064 | 13.42% |
| Total | 12 | 60.096 | 100% |
M = 3 × 12.011 + 1 × 15.999 + 8 × 1.008 = 60.096 g/mol

Frequently Asked Questions
What is the molar mass of Isopropyl alcohol?
The molar mass of Isopropyl alcohol (C3H8O) is 60.096 g/mol. That is the sum of the standard atomic weights of all 12 atoms in one formula unit: 3 × 12.011 + 1 × 15.999 + 8 × 1.008 = 60.096.
What is the molecular weight of Isopropyl alcohol?
60.096 — the same number as the molar mass, but as a dimensionless ratio rather than in g/mol. The two terms describe the same arithmetic, so a molecular weight of 60.10 and a molar mass of 60.10 g/mol are the same answer.
How many moles are in 100 g of Isopropyl alcohol?
100 ÷ 60.096 = 1.6640 mol. To convert any mass to moles, divide by the molar mass; to go the other way, multiply.
What is the percent composition of Isopropyl alcohol?
By mass, Isopropyl alcohol is 59.96% carbon, 26.62% oxygen, 13.42% hydrogen. Each element's share is its total mass in the formula divided by 60.096.
How many atoms are in one formula unit of Isopropyl alcohol?
12: 3 carbon, 1 oxygen, 8 hydrogen. One mole contains 6.02214076 × 10²³ formula units, so a mole of Isopropyl alcohol contains 12 × 6.022 × 10²³ atoms in total.
