Question: If a mixture is made by combining 5 liters of a 10% solution with 15 liters of a 20% solution, what is the overall percentage concentration of the solution?

Options:

Correct Answer: 16%

Solution:

Total acid = (0.10 * 5) + (0.20 * 15) = 0.5 + 3 = 3.5 liters. Total volume = 5 + 15 = 20 liters. Concentration = (3.5/20) * 100 = 17.5%.

Questions & Step-by-Step Solutions

If a mixture is made by combining 5 liters of a 10% solution with 15 liters of a 20% solution, what is the overall percentage concentration of the solution?

Step 1: Calculate the amount of acid in the 10% solution. Multiply 5 liters by 0.10 (10%). This gives you 0.5 liters of acid.
Step 2: Calculate the amount of acid in the 20% solution. Multiply 15 liters by 0.20 (20%). This gives you 3 liters of acid.
Step 3: Add the amounts of acid from both solutions together. 0.5 liters + 3 liters = 3.5 liters of acid.
Step 4: Calculate the total volume of the mixture. Add 5 liters and 15 liters together. This gives you 20 liters of total solution.
Step 5: Calculate the overall percentage concentration. Divide the total acid (3.5 liters) by the total volume (20 liters) and multiply by 100. (3.5 / 20) * 100 = 17.5%.
