Frequently Asked Questions
What is the molar mass of Zinc sulfate?
The molar mass of Zinc sulfate (ZnSO4) is 161.436 g/mol. That is the sum of the standard atomic weights of all 6 atoms in one formula unit: 1 × 65.380 + 4 × 15.999 + 1 × 32.060 = 161.436.
What is the molecular weight of Zinc sulfate?
161.436 — 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 161.44 and a molar mass of 161.44 g/mol are the same answer.
How many moles are in 100 g of Zinc sulfate?
100 ÷ 161.436 = 0.6194 mol. To convert any mass to moles, divide by the molar mass; to go the other way, multiply.
What is the percent composition of Zinc sulfate?
By mass, Zinc sulfate is 40.50% zinc, 39.64% oxygen, 19.86% sulfur. Each element's share is its total mass in the formula divided by 161.436.
How many atoms are in one formula unit of Zinc sulfate?
6: 1 zinc, 4 oxygen, 1 sulfur. One mole contains 6.02214076 × 10²³ formula units, so a mole of Zinc sulfate contains 6 × 6.022 × 10²³ atoms in total.
