Step 1: Define

1.450 mol Cd₃N₂

Step 2: Identify Conversions

Molar Mass of Cd - 112.41 g/mol

Molar Mass of N - 14.01 g/mol

Molar Mass of Cd₃N₂ - 3(112.41) + 2(14.01) = 365.25 g/mol

Step 3: Convert

Step 4: Check

Follow sig fig rules and round. We are given 4 sig figs.

529.613 g Cd₃N₂ ≈ 529.6 g Cd₃N₂
