    Answer:

    0.2 M

    Explanation:

    Step 1: Given data

    • Mass of sugar (sucrose): 15 g
    • Volume of water: 0.2 L (we will assume it is the volume of the solution)

    There are different ways to express the concentration of a solution. We will calculate molarity, which is one of the most used.

    Step 2: Calculate the moles of sucrose

    The molar mass of sucrose is 342.3 g/mol.

    15 g × 1 mol/342.3 g = 0.044 mol

    Step 3: Calculate the molarity of the solution

    Molarity is equal to the moles of solute divided by the liters of solution.

    M = 0.044 mol/0.2 L = 0.2 M
