Answer 2

Given,

A solution of 65%  ethyl or isopropyl alcohol is enough to destroy the virus.

Solution,

Calculate the alcohol present in a 100 ml solution.

Know that alcohol concentration is $\[65\% \]$.

In 1 ml solution $\[ = 0.65ml\]$ alcohol

In 100 ml solution,

$\[\begin{array}{l} = 0.65 \times 100\\ = 65ml\end{array}\]$

Hence 100 ml solution has 65 ml alcohol.
