Questions & Step-by-Step Solutions
In a mixture of two liquids, if the first liquid is 20% alcohol and the second is 50% alcohol, what is the overall percentage of alcohol in the mixture if equal volumes of both liquids are mixed?
Step 1: Identify the percentage of alcohol in the first liquid, which is 20%.
Step 2: Identify the percentage of alcohol in the second liquid, which is 50%.
Step 3: Since we are mixing equal volumes of both liquids, we can find the average percentage of alcohol.
Step 4: Add the two percentages together: 20% + 50% = 70%.
Step 5: Divide the total by 2 to find the average: 70% / 2 = 35%.
Step 6: The overall percentage of alcohol in the mixture is 35%.
