Question

A solution is made from 35ml of ethanol and 215ml of water. Calculate volume percentage?

Answer 1

Answer. 14%

Explanation: v.of solute/volume of solution*100=

35/250*100 = 14%

Answer 2

Given

• Volume of ethanol = 35 ml.

• Volume of water = 215 ml.

To Find

Volume percentage of the solution.

Formula

Volume percentage of solution = $\dfrac{Volume\:of\:Solute}{Volume\:of\:solution.}\;\times100$

Calculations

To find volume percentage of the solution , we need volume of solution.

$V_{Solution}\:=\:V_{Solute}\:+V_{Solvent}$

=> $V_{Solution}\:=\:35\:ml\:+\:215\:ml$

=> $V_{Solution}\:=250\:ml$

Thus, volume percentage of the solution = $\dfrac{Volume\:of\:Solute}{Volume\:of\:solution.}\:\times100$

= $\dfrac{35 ml}{250 ml}\:\times100$

= 14 ℅

Thus, volume percentage of the solution is 14 ℅.
