Question: What is the percentage concentration of a solution containing 15 g of solute in 150 g of solution? (2023)

Options:

Correct Answer: 15%

Solution:

Percentage concentration = (mass of solute / mass of solution) × 100 = (15 g / 150 g) × 100 = 10%

What is the percentage concentration of a solution containing 15 g of solute in 150 g of solution? (2023)

What is the percentage concentration of a solution containing 15 g of solute in 150 g of solution? (2023)

Step 1: Identify the mass of the solute. In this case, it is 15 g.
Step 2: Identify the total mass of the solution. Here, it is 150 g.
Step 3: Use the formula for percentage concentration: (mass of solute / mass of solution) × 100.
Step 4: Plug in the values: (15 g / 150 g) × 100.
Step 5: Calculate the division: 15 g divided by 150 g equals 0.1.
Step 6: Multiply the result by 100: 0.1 × 100 equals 10.
Step 7: Write the final answer: The percentage concentration is 10%.
