Frequently Asked Questions
What is the molar mass of Copper(II) sulfate?
The molar mass of Copper(II) sulfate (CuSO4) is 159.602 g/mol. That is the sum of the standard atomic weights of all 6 atoms in one formula unit: 4 × 15.999 + 1 × 63.546 + 1 × 32.060 = 159.602.
What is the molecular weight of Copper(II) sulfate?
159.602 — 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 159.60 and a molar mass of 159.60 g/mol are the same answer.
How many moles are in 100 g of Copper(II) sulfate?
100 ÷ 159.602 = 0.6266 mol. To convert any mass to moles, divide by the molar mass; to go the other way, multiply.
What is the percent composition of Copper(II) sulfate?
By mass, Copper(II) sulfate is 40.10% oxygen, 39.82% copper, 20.09% sulfur. Each element's share is its total mass in the formula divided by 159.602.
How many atoms are in one formula unit of Copper(II) sulfate?
6: 4 oxygen, 1 copper, 1 sulfur. One mole contains 6.02214076 × 10²³ formula units, so a mole of Copper(II) sulfate contains 6 × 6.022 × 10²³ atoms in total.
