Question

a solution contains 50 ml of alcohol mixed with 150 ml of water calculate the concentration of this solution

​

Answer 1

Answer:

Volume of solute = 50ml

Volume of solvent = 150ml

Volume of solution = Solvent + Solute

= 50 + 150 = 200

concentration = (Volume of solute/Volume of solution)100

= (50/200)100

= 25%

Answer 2

Answer:

concentration = v of solute/ v of sol×100

50/200×100

25%
