The solubility of sucrose (common table sugar) at 70 degrees Celsius is 320 g/100 g H2O.
a. How much sucrose can dissolve in 200 g of water at 70 degrees celsius?
b. Will 400 g of sucrose dissolve in a teapot that contains 200 g of water at 70 degrees celsius? Explain.

a) its a simple ratio. 320/100 = X/200
cross multiply you get 640. (Alternatively, obviously the amount of water was just doubled, so the amount of sucrose that can be dissolved is doubled)
b) Yes, as we can see from part a, 200 g of water can dissolve 640 grams of water at 70 degrees, so 400g should easily be able to dissolve.

a. double the mass ---> 640g.
b. 400 is less than 640, so yes!
