1.69 g Na₂O

General Formulas and Concepts:

Chemistry - Atomic Structure

Explanation:

Step 1: Define

0.0273 mol Na₂O

Step 2: Identify Conversions

Molar Mass of Na - 22.99 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of Na₂O - 2(22.99) + 16.00 = 61.98 g/mol

Step 3: Convert

= 1.69205 g Na₂O

Step 4: Check

We are given 3 sig figs. Follow sig fig rules and round.

1.69205 g Na₂O ≈ 1.69 g Na₂O
