What is the molarity of 2.0 moles of glucose
in 4.0 L of glucose solution?

0.5 M

General Formulas and Concepts:

Chemistry - Aqueous Solutions

Molarity = moles of solute / liters of solution

Explanation:

Step 1: Define

2.0 mol glucose

4.0 L glucose solution

Step 2: Find Molarity

Substitute:                    M = 2.0 mol / 4.0 LDivide:                           M = 1/2Evaluate:                       M = 0.5

Yes she is correct. the answer is completely correct
