What is the number of moles of Glucose in .500 L of a .40 M solution?

Answer 1

1. Molarity (M) = Moles of Solute (mol) / Liters of Solution (L)
2. List Known Quantities into Above Equation
3. Molarity of Glucose Solution = 0.4 M
4. Liters of Glucose Solution = 0.5 L
5. Substitute Known Quantities into Above Equation
6. 0.4 M = x mol / 0.5 L
7. Solve for unknown value "x"
8. 0.5 * 0.4 = x
9. x = 0.2 mol of Glucose in the Solution

Answer 2

1 L is the volume containing 0.40 moles of glucose

Therefore, .500 L will contain 0.40 x 0.500 = 0.20 moles of glucose

You are given the molarity and asked to find the number of moles in half the volume of solution.
