Question: What is the percentage concentration of a solution containing 20 g of solute in 200 g of solution? (2021)

Options:

Correct Answer: 10%

Solution:

Percentage concentration = (mass of solute / mass of solution) × 100 = (20 g / 200 g) × 100 = 10%.

What is the percentage concentration of a solution containing 20 g of solute in 200 g of solution? (2021)

What is the percentage concentration of a solution containing 20 g of solute in 200 g of solution? (2021)

Step 1: Identify the mass of the solute. In this case, it is 20 g.
Step 2: Identify the total mass of the solution. Here, it is 200 g.
Step 3: Use the formula for percentage concentration: (mass of solute / mass of solution) × 100.
Step 4: Substitute the values into the formula: (20 g / 200 g) × 100.
Step 5: Calculate the division: 20 g divided by 200 g equals 0.1.
Step 6: Multiply the result by 100 to find the percentage: 0.1 × 100 equals 10%.
Step 7: Conclude that the percentage concentration of the solution is 10%.
