    Dissolve 300 g of salt in 10L of water. Find density of resulting solution.

    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 doesnít 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. Donít 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.

    Have you considered division?

    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!
