Question

a solution contain 5.6ml of a alcohol mixed with 75ml of water calculate concentration of solutions

Answer 1

Volume of alcohol =5.6 ml 

Volume of water = 75ml 

Total volume of solution = volume of water +volume of alcohol = 80.6 ml

percentage concentration (by volume)  =(5.6/80.6) x100 = 6.94%

Answer 2

Given - Volume of solute and solvent

Find - Concentration of solution

Solution - Concentration of solution can be calculated as - volume of solute/volume of solution*100

Volume of solution = volume of solute + volume of solvent

Volume of solution = 5.6 + 75

Volume of solution = 80.6 ml

Keep the values in formula to find the concentration of solution.

Concentration of solution = 5.6/80.6*100

Concentration of solution = 6.9%

Hence, the concentration of solution is 6.9%.
