Questions & Step-by-Step Solutions
If a solution is made by mixing 30% and 70% solutions in equal volumes, what is the percentage concentration of the resulting solution?
Step 1: Understand that you have two solutions: one is 30% concentration and the other is 70% concentration.
Step 2: Since you are mixing them in equal volumes, you will take the same amount of each solution.
Step 3: To find the average concentration of the mixed solution, you add the two percentages together: 30% + 70%.
Step 4: Now, divide the total by 2 to find the average: (30% + 70%) / 2.
Step 5: Calculate the result: (100%) / 2 = 50%.
Step 6: Therefore, the percentage concentration of the resulting solution is 50%.
