Answer

Explanation:

Step1: Determine the percentage of water

The solution is 70% rubbing - alcohol by volume. So the percentage of water is $100% - 70%=30%$.

Step2: Calculate the volume of water

The total volume of the solution is 946 ml. To find the volume of water, we multiply the total volume by the percentage of water. The volume of water $V = 946\times0.3$. $V=283.8$ ml

Answer:

A. 283.8 ml
