Question

a solution contains 5.6ml of alcohol mixed with 75ml of water calculate the concentration of this solution.​

Answer 1

`\huge \boxed{6.948 \%}}`

Step-by-step explanation:

Volume of solute (Alcohol) ⇒ 5.6 ml

Volume or solvent (Water) ⇒ 75 ml

Total volume of solution ⇒ 5.6 ml + 75 ml ⇒ 80.6 ml

`\displaystyle \sf Concentration \ of \ solution \ (\%)= (Volume \ of \ solute)/(Volume \ of \ solution) * 100`

`\displaystyle \sf Concentration \ of \ solution \ (\%)= (5.6)/(80.6) * 100=(5600)/(806) = 6.947891`
