Question

what is the concentration, in percent (v/v), of a solution containing 50 mL of diethyl ether (C4H10O) in 2.5 L of solution?

Answer 1

Volume of solute = 50 mL

Volume of solution = 2.5 L x 1000 = 2500 mL

( V / V ) = ( 50 / 2500 ) x 100

( V/ V) =0.02 x 100 =  2.0 %

hope this helps!

Answer 2

Answer: The v/v in percent of diethyl ether in a solution is 2%.

Explanation:

To calculate the percentage volume by volume of a solute in a solution, we use the formula:

$\%(v/v)=\frac{\text{Volume of solute (in mL)}}{\text{Volume of solution (in mL)}}\times 100$

We are given:

Volume of solute = 50 mL

Volume of solution = 2.5 L = 2500 mL     (Conversion factor: 1 L = 1000 mL)

Putting values in above equation, we get:

$\%(v/v)=\frac{50mL}{2500mL}\times 100=2\%$

Hence, the v/v in percent of diethyl ether in a solution is 2%.
