I only got 50 points (which is not 100). :-)
Look at the graph. At 80 °C, about 38 g of solute is able to dissolve, and that’s for ever 100 g of water. That means that for every 150 grams of water, 57 grams of solute can dissolve (38/2 = 19 + 38 = 57 g) at 80 °C. Since 57 g is greater than 55 g, all for he sodium chloride should dissolve in 150 g of water at 80 °C - you can put all of that into a “mathematical explanation”.
The given formula contains two carbon along with six hydrogen and an oxygen.
The possible isomers from 
are ethanol and dimethyl ether.
Ehtanol is an alcohol containing a hydroxyl group whereas dimethyl ether is an ether containing an oxygen between two methyl
The structure of two isomers are:
It is a trial aimed to reduce bias during an experiment. An example would be a sugar pill, something that has no real effect so that the results of the true trial can accurately be compared. Its like a control group.
Given that
1 skvarnick = 45 quibs
3 quibs = 7 sleps
Now if we have 45 quibs it means we have you have one skvarnick
three quibs = 7 sleps
so one quib = 7/3 sleps
so 45 quibs = 7 X 45 / 3 = 105 sleps
