this is a follow up question from my last one with the exact question

If you dissolve 200 g of salt in 20 l of water, what is the density of that solution of salty water? Hint: In this particular example, assume that the total volume doesn’t change when salt is added to water. You will need the mass of salt and the mass of water to find the mass of the solution of salty water. Don’t forget to show your working and include units.
