Frequently Asked Questions
What is the molar mass of Ascorbic acid?
The molar mass of Ascorbic acid (C6H8O6) is 176.124 g/mol. That is the sum of the standard atomic weights of all 20 atoms in one formula unit: 6 × 15.999 + 6 × 12.011 + 8 × 1.008 = 176.124.
What is the molecular weight of Ascorbic acid?
176.124 — 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 176.12 and a molar mass of 176.12 g/mol are the same answer.
How many moles are in 100 g of Ascorbic acid?
100 ÷ 176.124 = 0.5678 mol. To convert any mass to moles, divide by the molar mass; to go the other way, multiply.
What is the percent composition of Ascorbic acid?
By mass, Ascorbic acid is 54.50% oxygen, 40.92% carbon, 4.58% hydrogen. Each element's share is its total mass in the formula divided by 176.124.
How many atoms are in one formula unit of Ascorbic acid?
20: 6 oxygen, 6 carbon, 8 hydrogen. One mole contains 6.02214076 × 10²³ formula units, so a mole of Ascorbic acid contains 20 × 6.022 × 10²³ atoms in total.
