Frequently Asked Questions
What is the molar mass of Ethyl acetate?
The molar mass of Ethyl acetate (C4H8O2) is 88.106 g/mol. That is the sum of the standard atomic weights of all 14 atoms in one formula unit: 4 × 12.011 + 2 × 15.999 + 8 × 1.008 = 88.106.
What is the molecular weight of Ethyl acetate?
88.106 — 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 88.11 and a molar mass of 88.11 g/mol are the same answer.
How many moles are in 100 g of Ethyl acetate?
100 ÷ 88.106 = 1.1350 mol. To convert any mass to moles, divide by the molar mass; to go the other way, multiply.
What is the percent composition of Ethyl acetate?
By mass, Ethyl acetate is 54.53% carbon, 36.32% oxygen, 9.15% hydrogen. Each element's share is its total mass in the formula divided by 88.106.
How many atoms are in one formula unit of Ethyl acetate?
14: 4 carbon, 2 oxygen, 8 hydrogen. One mole contains 6.02214076 × 10²³ formula units, so a mole of Ethyl acetate contains 14 × 6.022 × 10²³ atoms in total.
