Answer:

80.1 g/mol

General Formulas and Concepts:

Chemistry - Atomic Structure

  • Reading a Periodic Table

Explanation:

Step 1: Define

NH₄NO₃

Step 2: Identify Conversions

Molar Mass of N - 14.01 g/mol

Molar Mass of H - 1.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of NH₄NO₃ - 2(14.01) + 4(1.01) + 3(16.00) = 80.06 g/mol

Step 3: Check

We want 1 sig fig. Follow sig fig rules and round.

80.06 g/mol ≈ 80.1 g/mol
