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

Academic Chemistry NCERT Class 9

Volume of alcohol = 5.6 ml

Volume of water = 75 ml

So, volume of solution = 75ml + 5.6 ml = 80.6 ml

$concentration= \frac {volume\ of\ solute}{volume\ of\ solution}×100$

=5.680.6×100

=6.9%

Hence, the concentration is 6.9%

Concentration of Solution and the Calculation
The teacher instructed three students ‘A’, ‘B’ and ‘C’ respectively to prepare a 50% (mass by volume) solution of sodium hydroxide (NaOH). ‘A’ dissolved 50g of NaOH in 100 mL of water, ‘B’ dissolved 50g of NaOH in 100g of water while ‘C’ dissolved 50g of NaOH in water to make 100 mL of solution. Which one of them has made the desired solution and why?
