A #"5 gallon"# volume of benzene is accidentally added to an aquifer whose volume is #3.79xx10^8*L#. If homogeneous mixing is assumed, what is the #"ppm concentration"# with respect to benzene?
1 Answer
Whoops! I wonder if this an actual scenario?
Explanation:
This question is bound to be problematic because metric and US (?) systems of volume measurement have been used. We assume that the benzene is homogeneously mixed through the aquifer.
Now, 1 US gallon
So volume of aquifer
And
So mass of benzene
So we've got (finally)
This is well under
