Frequently Asked Questions
What is the molar mass of Ethylene?
The molar mass of Ethylene (C2H4) is 28.054 g/mol. That is the sum of the standard atomic weights of all 6 atoms in one formula unit: 2 × 12.011 + 4 × 1.008 = 28.054.
What is the molecular weight of Ethylene?
28.054 — 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 28.05 and a molar mass of 28.05 g/mol are the same answer.
How many moles are in 100 g of Ethylene?
100 ÷ 28.054 = 3.5646 mol. To convert any mass to moles, divide by the molar mass; to go the other way, multiply.
What is the percent composition of Ethylene?
By mass, Ethylene is 85.63% carbon, 14.37% hydrogen. Each element's share is its total mass in the formula divided by 28.054.
How many atoms are in one formula unit of Ethylene?
6: 2 carbon, 4 hydrogen. One mole contains 6.02214076 × 10²³ formula units, so a mole of Ethylene contains 6 × 6.022 × 10²³ atoms in total.
