Question

How many mL of alcohol are in 240 mL of 95.0% alcohol solution?

Answer 1

To work it out, you divide 240 by 100 to work out 1% of it, then multiply that by 95 to work out 95% of it. So
(240/100) * 95 = 228mL

Answer 2

Answer:228 mL of alcohol are in 240 mL of 95.0% alcohol solution.

Explanation:

Total volume of the solution = 240 mL

Percentage of alcohol in solution = 95.0%

Volume of volume of alcohol in solution = V

$95.0\%=\frac{V}{240 mL}\times 100$

V = 228 mL

228 mL of alcohol are in 240 mL of 95.0% alcohol solution.
