AgNO₃ molar mass FAQ
What is the molar mass of silver nitrate (AgNO₃)?
169.872 g/mol. It is the sum of the atomic masses of every atom in the formula: 1 × 107.868 + 1 × 14.007 + 3 × 15.999 = 169.872 g/mol.
How many grams are in one mole of AgNO₃?
169.872 g. Molar mass is the mass of one mole (6.022 × 10²³ formula units), so 1 mol of AgNO₃ weighs 169.872 g and 0.5 mol weighs 84.936 g.
How many moles are in 10 g of AgNO₃?
10 g ÷ 169.872 g/mol = 0.05887 mol.
What is the percent composition of AgNO₃?
Silver 63.50%, Nitrogen 8.25%, Oxygen 28.25%.
Is molecular weight the same as molar mass for AgNO₃?
Numerically yes: the molecular (or formula) weight is 169.872 u per formula unit, and the molar mass is 169.872 g/mol.
