Question

A solution is made by adding 35 mL of benzene to 90 mL of toluene. What is the percent by volume of benzene?

Answer 1

∴ The percent concentration by volume of benzene is 31.25%

Answer 2

38.89% is the percent by volume of benzene in the $90ml$ of toluene.

Given:

From the given question,

The $35ml$ of benzene is added to the $90ml$   of toluene solution.

The Volume of the given solution $=90ml$

The Volume of benzene$=35ml$

To find:

The percent by volume of benzene

Step-by-step explanation:

Percent Volume of concentration$=\[\frac{35}{90}\times 100=38.89\]$ %

Hence, The percent Concentration by volume of benzene in toluene is 38.89%
