So the question is basically asking you to find the error in the way a student solves a chemistry question. I correctly identified the issue which was not converting kg to g. I did so but as seen in the pictures the 759 g/L becomes 759*g*L^-1. Why did the grams not cancel out and why did it go from g/L to g*L^-1, also why is there a negative 1?
Sorry if this is asking a lot.

Yes, grams should cancel out, apparently the solution is not complete.

g/L and g L^-1 are different ways of writing the same thing, unless I am missing something.

This is a basic exponent rule.
[tex]\frac{1}{x} = x^{-1}[/tex]
So,
[tex]\frac{g}{L} = g \frac{1}{L} = g L^{-1}[/tex]
Additionaly, recall that
[tex]\frac{a}{\frac{b}{c}} = \frac{ac}{b}[/tex]
If you are using software, it is possible that it can't equate kg to g, which means you have to convert g/L to kg/L.
