Q. Darius buys a bottle of a chemical solution that contains 70% alcohol. The bottle contains 500 milliliters of solution.How many milliliters of alcohol are in the solution?milliliters
Identify Problem: Understand the problem and identify the given values.We are given a 500 milliliter solution that contains 70% alcohol. We need to find out how many milliliters of alcohol this represents.
Use Percent Formula: Use the percent formula to find the part of the solution that is alcohol.The percent formula is: Percent (as a decimal) × Whole = PartHere, the percent (as a decimal) is 70% or 0.70, and the whole is the total volume of the solution, which is 500 milliliters.
Calculate Alcohol Amount: Calculate the amount of alcohol in milliliters.Using the formula from Step 2, we multiply the decimal form of the percentage by the total volume of the solution:0.70×500 milliliters = 350 milliliters
Verify Calculation: Verify the calculation to ensure there are no math errors.Rechecking the calculation: 0.70×500=350. The calculation is correct.
