Question

Determine the molarity of 1.2 mol KCl in 1.1 L of a solution?

Answer 1

1.1 M

General Formulas and Concepts:

• Molarity = moles of solute / liters of solution

Step-by-step explanation:

Step 1: Define variables

1.2 mol KCL

1.1 L of solution

M = unknown

Step 2: Solve for Molarity

1. Substitute: M = 1.2 mol/1.1 L
2. Evaluate: M = 1.09091

Step 3: Check

We are given 2 sig figs. Follow sig fig rules.

1.09091 M ≈ 1.1 M
