Answer 1

Answer:

Answer: 15% alcohol solution means that there is 15 mL of alcohol present in the 100 mL of alcohol solution.

In every 100 mL of alcohol solution there is 15% of alcohol present in it:

15\%\text{of the 100 mL}=100\times \frac{15}{100}=15 mL15%of the 100 mL=100×

100

15

=15mL

Alcohol present in 100 mL alcohol solution = 15 mL

Water present in in 100 mL alcohol solution = 100 - 15 = 85 mL
