How 164.086 g/mol is worked out
| Element | Atoms | Atomic mass | Mass | % of total |
|---|---|---|---|---|
| Oxygen | 6 | 15.999 | 95.994 | 58.50% |
| Calcium | 1 | 40.078 | 40.078 | 24.42% |
| Nitrogen | 2 | 14.007 | 28.014 | 17.07% |
| Total | 9 | 164.086 | 100% |
M = 6 × 15.999 + 1 × 40.078 + 2 × 14.007 = 164.086 g/mol

Frequently Asked Questions
What is the molar mass of Calcium nitrate?
The molar mass of Calcium nitrate (Ca(NO3)2) is 164.086 g/mol. That is the sum of the standard atomic weights of all 9 atoms in one formula unit: 6 × 15.999 + 1 × 40.078 + 2 × 14.007 = 164.086.
What is the molecular weight of Calcium nitrate?
164.086 — 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 164.09 and a molar mass of 164.09 g/mol are the same answer.
How many moles are in 100 g of Calcium nitrate?
100 ÷ 164.086 = 0.6094 mol. To convert any mass to moles, divide by the molar mass; to go the other way, multiply.
What is the percent composition of Calcium nitrate?
By mass, Calcium nitrate is 58.50% oxygen, 24.42% calcium, 17.07% nitrogen. Each element's share is its total mass in the formula divided by 164.086.
How many atoms are in one formula unit of Calcium nitrate?
9: 6 oxygen, 1 calcium, 2 nitrogen. One mole contains 6.02214076 × 10²³ formula units, so a mole of Calcium nitrate contains 9 × 6.022 × 10²³ atoms in total.
