Understanding Molarity

Molarity (M) is a measure of concentration defined as moles of solute per liter of solution.

Calculation

1. Moles of solute: You have 25 moles of sucrose.

2. Liters of solution: You have 50 liters of water. Since the sucrose dissolves in the water, the total volume of the solution is essentially 50 liters.

3. Molarity:

Molarity (M) = (Moles of solute) / (Liters of solution)

M = 25 moles / 50 liters

M = 0.5 M

Therefore, the molarity of the sucrose solution is 0.5 M.
