Hi Destiny, this seems to be a tricky conversion problem so let's break it down one step at a time:

- The problem asks you to convert from one 'type' of density, lb/gal, to another 'type, of density, g/mL.

- lb -- g, both correspond to a weight of something
- gal -- mL, both correspond to volume of something

Let's set up some conversions before we get going with this problem:

- 1 lb = 453.59237 grams
- 1 gallon (gal) = 3785.41 mL

Now, from here on it's multiplying and canceling out terms:

72 lb / gal * (453.59237 grams / 1 lb) * (1 gal / 3785.41 mL) =

**8.6275 g / mL**
