wah... thanksWon't it be x2= 4 (1-x)^2 -> x= 2(1-x) -> x= 2-2x -> 3x=2 -> x=2/3?

question 23:
i am working on it Metanoia
i had to erase some answer because you had already answered them. please tell me which one you are doing so i do other queries instead.
Maybe we can quote and "click reply" immediately.
And then take your time to add the answers by editing the posts.
If it turns out we are repeating answers even after that, just leave them posted. Sometimes, it might be good to have differing approaches to the same questions.

thats they way i am doing. adding each question one by one. but instead on new post because the answer won't get notification when i add new answer to the same post.
Q8) Use of the Data Booklet is relevant to this question.
The approximate percentage composition of the atmosphere on four different planets is given in
the table below.
The density of a gas may be defined as the mass of 1 dm3
of the gas measured at s.t.p.
Which mixture of gases has the greatest density?
planet major gases / % by number of molecules
A Jupiter H2 89.8, He 10.2
B Neptune H2 80.0, He 19.0, CH4 1.0
C Saturn H2 96.3, He 3.25, CH4 0.45
D Uranus H2 82.5, He 15.2, CH4 2.3
