Question

What is the percentage by volume of a 400ml acid added to 1600ml water ?

Answer 1

Answer:

25%

Explanation:

(400/1600)*100=25%

Answer 2

The percentage by volume of a 400ml acid added to 1600ml water is 20% ?

Volume of solute (acid) = 400 mL.

Volume of solvent (water) = 1600 mL.

The (volume/volume)% representation of strength of a solution is given by:

$\frac{Volume of solute}{ Volume of solution}$ × 100%

= $\frac{Volume of solute}{Volume of solute + Volume of solvent}$ × 100%

= $\frac{400}{400 + 1600}$ × 100%

= $\frac{400}{2000}$ × 100%

= 20%

Hence the (volume/volume)% strength is 20%
