Solubility Table . . . need help please!?
This is the question I have to answer:
What is the minimum mass of water that will dissolve 80.0 grams of sucrose and 40.00 g of salt at 80 degrees celsius?

Given the following:
Solubility table
(g solute/ 100g of water)

Temp, Potassium dichromate, Sucrose, NaCl
0, 4.6, 181, 35.6
10, 6.6, 189, 35.7
20, 12.2, 200, 35.8
40, 26, 234, 36.3
60, 46.5, 289, 37.1
80, 70, 369, 38.0
100, 97, 476, 39.4

I have used commas to separate the columns
Please help! I don't understand how to do this.

You will see that 100g of water will easily dissolve 80g of sucrose at 80C, but it won't quite dissolve 40g of salt.

You will have to scale up the mass of water by multiplying the following:

(40/38) x 100.

on your first question, i do no longer think of that there is a formula. Solubility is the utmost quantity of solute which would be dissolved in a given quantity of solvent at a definite temperature. actually, saying that the solubility of KNO3 is 50g/100g is incomplete. The temperature must be pronounced. For the 2nd question, with the aid of ratio and proportion, 4kg of sugar must be dissolved in 2kg of sugar to have a saturated answer. subsequently, the utmost quantity of water which you could use to make a supersaturated sugar answer is 2kg.
