HELP!!! how do i find density of this problem?

Question

i have a chemistry test tomorrow and i have no clue how to do this?
can you please explain how you would do this problem:

Find density of 25g of copper in 4.8 liters of H2O??

Answer 1

density = mass / volume
Grams are a measure of mass, while volume can be measured in liters.
= 25g / 4.8L
= 5.2 g/L

Answer 2

Density = Mass / Volume

So just divide 25 g / 4.8 liters and you have an answer.

Most of the time, density is expressed as g /mL. If that's what you want, first change the 4.8 liters to 4800 mL and do the division.
