Question

A solution contains 5.6 ml of alcohol mixed with 75 ml of water. Calculate the concentration of this solution.​

Answer 1

Answer:

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) * 100 = 6.94%

Answer 2

Answer:

Volume of alcohol \(= 5.6\) ml

Volume of water \(= 75\) ml

so, volume of solution \(= 75\,\mathrm{ml} + 5.6\,\mathrm{ml} = 80.6\) ml

concentration \(=\mathrm{volume\,of\,solutevolume\,of\,solute}+\mathrm{volume\,of\,solvent} \times 100\)

\(=5.6+80.6 \times 100\)

\(=6.9{\%}\)
