If you dissolve 300 g of salt in 10 litres of water, what is the density of that solution of salty water? 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.
 
Have you tried anything, yet? It would be helpful for us to see where you got stuck. :cool:

What is the mass of 10 liter of water?

When you reply with the previously-requested information, please also state the topic in calculus that generated this homework exercise, so we can try to guess how this involves calculus (rather than simple pre-algebra and some chemistry constants). Thank you! ;)
