Paper 5 question!

[Ash1994]

In question 2 in the table how do we calculate the solubility in g/100?
I got 7 for the first one which i doubt!

guys please solve this question 2 of p5 and kindly make graph for this question and other related questions to the graph should be solved http://www.xtremepapers.com/papers/...d AS Level/Chemistry (9701)/9701_s09_qp_5.pdf

thanku waiting for a quick response

temprature in X axis and solubity in Y axis

temprature in X axis and solubity in Y axis

i know that..i meant numerical values... i cant think of a suitable scale such that 75% of graph is covered!!

you dont have to exactly plot it just estimate what type of graph it will be. You can either make it a increasing curve or linear straight line as solubility increases as temprature increases

yes it is 7! i just did that question: 100(mass of solute\mass of water)
