Frequently Asked Questions
What is the molar mass of Glycerol?
The molar mass of Glycerol (C3H8O3) is 92.094 g/mol. That is the sum of the standard atomic weights of all 14 atoms in one formula unit: 3 × 15.999 + 3 × 12.011 + 8 × 1.008 = 92.094.
What is the molecular weight of Glycerol?
92.094 — 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 92.09 and a molar mass of 92.09 g/mol are the same answer.
How many moles are in 100 g of Glycerol?
100 ÷ 92.094 = 1.0858 mol. To convert any mass to moles, divide by the molar mass; to go the other way, multiply.
What is the percent composition of Glycerol?
By mass, Glycerol is 52.12% oxygen, 39.13% carbon, 8.76% hydrogen. Each element's share is its total mass in the formula divided by 92.094.
How many atoms are in one formula unit of Glycerol?
14: 3 oxygen, 3 carbon, 8 hydrogen. One mole contains 6.02214076 × 10²³ formula units, so a mole of Glycerol contains 14 × 6.022 × 10²³ atoms in total.
