1.87 A solution of ethanol in water has a volume of 54.2 mL and a mass of 49.6 g. what information would you need to look up and how would you determine the percentage of ethanol in this solution?

Interpretation Introduction

Interpretation:

Determine the percentage of ethanol in this solution

Concept introduction:

% of ethanol in solution(by mass)=mass of ethanol in solutionmass of solution×100% of ethanol in solution(by volume)=volume of ethanol in solutionvolume of solution×100

Explanation of Solution

% of ethanol (by mass)=mass of pure ethanol (gm)mass of solution(gm)×100

You know the mass of solution, so to know the % of ethanol you have to find out mass of pure ethanol
