the total solution volume will be 100ml
since were adding 25ml of ethanol then the volume of water used in will be 100-25=75ml
the percentage by volume of the solution is 25/100 X 100/1 = 25%
0.250 L = 250 mL
So, 15 mL of ethanol in (15 + 250) mL = 265 mL
So percentage = 100*15/265 = 5.6603% approx.
0.250 L = 250 mL
So, 15 mL of ethanol in (15 + 250) mL = 265 mL
So percentage = 100*15/265 = 5.6603% approx.
0.250 L = 250 mL

0250 as a percentage = 2.5%0.0250 * 100% = 2.50%
