Question What is the concentration of a solution in which 15 grams of sugar is dissolved in 0.2 L of water?

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 Log in to Reply

Answer:0.2 M

Explanation:Step 1: Given dataThere 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 sucroseThe 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 solutionMolarity is equal to the moles of solute divided by the liters of solution.

M = 0.044 mol/0.2 L = 0.2 M
