Answer to Question #131231 in General Chemistry for Unknown

Question

 Using a 15% ethyl alcohol and water solution,find percent by volume and proof of solution. 

Answer 1

 Using a 15% ethyl alcohol and water solution,find percent by volume and proof of solution.

Ethyl alcohol = 15%

15%= volume of solute/ volume of solution × 100

assumed that volume of solution 100 ml

then volume of ethyl alcohol is

15 ml

% by volume of ethyl alcohol 15% and water is 85%

% of ethyl acohol in 85 % water

= 15/85×100

= 12.75% with respect to solvent (water)
