Afish tank holds 29 gal of water. using the density of 1.00 g/ml for water, determine the number of pounds of water in the fish tank.

The problem is giving us the volume, the density and is asking us for the mass. For this we can use the density equation () so we solve for mass which is our unknown().

We can´t just multiply this two because they are in different units so we solve this first by turning [gal] to [ml] with the equivalence of 1gal=3785.41 ml

Now we can multiply:

The answer is requested in [pounds] so we solve this by turning [g] to [pounds] with the equivalence of 453.592 g =1 pound
