Option D
Step by step explanation:
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
