Frequently Asked Questions
What is the molar mass of Silver nitrate?
The molar mass of Silver nitrate (AgNO3) is 169.874 g/mol. That is the sum of the standard atomic weights of all 5 atoms in one formula unit: 1 × 107.870 + 3 × 15.999 + 1 × 14.007 = 169.874.
What is the molecular weight of Silver nitrate?
169.874 — 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 169.87 and a molar mass of 169.87 g/mol are the same answer.
How many moles are in 100 g of Silver nitrate?
100 ÷ 169.874 = 0.5887 mol. To convert any mass to moles, divide by the molar mass; to go the other way, multiply.
What is the percent composition of Silver nitrate?
By mass, Silver nitrate is 63.50% silver, 28.25% oxygen, 8.25% nitrogen. Each element's share is its total mass in the formula divided by 169.874.
How many atoms are in one formula unit of Silver nitrate?
5: 1 silver, 3 oxygen, 1 nitrogen. One mole contains 6.02214076 × 10²³ formula units, so a mole of Silver nitrate contains 5 × 6.022 × 10²³ atoms in total.
