Click on the graphic to choose the correct relationship on the graph. r = diffusion rate of gas mw = molecular weight

graph 2

Explanation:

Graham's law:

∴v1: gas diffusion rate 1

∴ v2: gas diffusion rate 2

∴ M1: gas molecular weight 1

∴ M2: gas molecular weight 2

Let Y = R = v1/v2 and X = M2/M1

⇒ Y = √X

the graph for the function Y = √X;  is as shown in graph 2.

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.
