Answer:
Step-by-step explanation:
Here,we want to get the volume of water that contains 250 mg of benzene
From the question,we have it that the percentage by mass of benzene in water is 4.5 * 10^-5%
This corresponds to the 250 mg (this is same as 250/1000 = 0.25 g)
Let us say the mass of the water that contains the benzene is x g
4.5 * 10^-5% = 0.25 g
100% = x g
To get x, we have it that:
We have to get the volume from this
Mathematically, volume will be mass divided by density (given as 1 g/mol)
Thus,we have the volume as:
