Question

What is the mass of 0.73 moles of AgNO3?

Answer 1

124 g (3 sig figs)

or

124.011 g (6 sig figs

Step-by-step explanation:

Step 1: Calculate g/mol for AgNO₃

Ag - 107.868 g/mol

N - 14.01 g/mol

O - 16.00 g/mol

107.868 + 14.01 + 16.00(3) = 169.878 g/mol

Step 2: Multiply 0.73 moles by molar mass

0.73 mol (169.979 g/mol)

124 grams of AgNO₃
