$$2.18\%$$

Explanation:

Volume of isopropyl alcohol = 24 mL

Volume of water = 1.1 L

Percentage of isopropyl alcohol is given by

$$\dfrac{\text{Volume of isopropyl alcohol}}{\text{Volume of isopropyl alcohol+Volume of water}}\times 100\\= \dfrac{24\times 10^{-3}}{1.1+2.4\times 10^{-3}}\times 100\\ =2.18\%$$

The percent by volume of isopropyl alcohol in the given solution is $$2.18\%$$.
