Frequently Asked Questions
What is the molar mass of Acetone?
The molar mass of Acetone (C3H6O) is 58.080 g/mol. That is the sum of the standard atomic weights of all 10 atoms in one formula unit: 3 × 12.011 + 1 × 15.999 + 6 × 1.008 = 58.080.
What is the molecular weight of Acetone?
58.080 — 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 58.08 and a molar mass of 58.08 g/mol are the same answer.
How many moles are in 100 g of Acetone?
100 ÷ 58.080 = 1.7218 mol. To convert any mass to moles, divide by the molar mass; to go the other way, multiply.
What is the percent composition of Acetone?
By mass, Acetone is 62.04% carbon, 27.55% oxygen, 10.41% hydrogen. Each element's share is its total mass in the formula divided by 58.080.
How many atoms are in one formula unit of Acetone?
10: 3 carbon, 1 oxygen, 6 hydrogen. One mole contains 6.02214076 × 10²³ formula units, so a mole of Acetone contains 10 × 6.022 × 10²³ atoms in total.
