60 mg x 2 x 2 x 2 = 480 mg of drug injected

Which equations did you use?

You don't really need an equation to solve this one. Just look look at the units. The answer needs to be in mg and you are given mg/L and L in the stem.

t1/2 is 2hrs and it has been 6hrs since the drug was injected. It has been 3 t1/2
