0.49 mol HCl

General Formulas and Concepts:

Chemistry - Atomic Structure

Explanation:

Step 1: Define

18 g HCl

Step 2: Identify Conversions

Molar Mass of H - 1.01 g/mol

Molar Mass of Cl - 35.45 g/mol

Molar mass of HCl - 1.01 + 35.45 = 36.46 g/mol

Step 3: Convert

= 0.493692 mol HCl

Step 4: Check

Round our answer to 2 decimal places.

0.493692 mol HCl ≈ 0.49 mol HCl
