If Carl buys a 946 ml bottle of rubbing alcohol, how much of the aqueous solution is water?

The question is incomplete, here is the complete question:

A bottle of rubbing alcohol having aqueous solution of alcohol contains 70% (v/v) alcohol. If Carl buys a 946 ml bottle of rubbing alcohol, how much of the aqueous solution is water?

The amount of water present in the given bottle of rubbing alcohol is 283.8 mL

Explanation:

We are given:

Volume of bottle of rubbing alcohol = 946 mL

70% (v/v) alcohol solution

This means that 70 mL of rubbing alcohol is present in 100 mL of solution

Amount of water present in solution = [100 - 70] = 30 mL

Applying unitary method:

In 100 mL of solution, the amount of water present is 30 mL

So, in 946 mL of solution, the amount of water present will be =

Hence, the amount of water present in the given bottle of rubbing alcohol is 283.8 mL

the answers would be

the first one and the second one
