Question

What is the correct unit for the following solution?

$100ml$ of ethanol dissolved in $1l$ of gasoline.

• A. $w/w$
• B. $m$
• C. $M$
• D. $v/v$

Answer 1

The correct option is D $v/v$

When one measures $\%$ of solution using both volume units then the units of solution will be $v/v$ i.e. volume/volume.

Here, we used mL and Litre which are both volume units.

Here 100 ml of ethanol dissolved in 1 L of gasoline this solution is represented in the form of $v/v$ unit.

So, the unit is $v/v$.
