The answer is Option A my brother. If you are not sure of your answer, you should have made research before doing this. This is the analysis Now, 1 mole of any gases/elements at s.t.p contains 22.4dm^3 or 6.02* 10^23 atoms 1 mole of C4H10 contains 6.02* 10^23 atoms 4 moles of Cl2 contains 2.402 * 10^24 atoms 3 moles of O3 contains 1.81 * 10^23 atoms 7 moles of Ar contains 4.21 * 10^23 atoms Therefore, option A contains the least number of atoms
49 I don't understand your calculator base on time.. ...I taught to change hour to seconds is by 60 x60 Which is 3600 x2,cause is 2hr ....then plus by 30 mins after converting to seconds... that will give the final time
We converted 2h to minutes (120m) then plus the extra 30 (150m), we converted 150m minutes to seconds by multiplying by 60. your method is correct so as ours.
For no. 48, the myschool website says the answer is 1.8g (C) but you got D. Which is the right one? This is the link: myschool.ng/classroom/chemistry/55813 why'd u delete the comment😬
Thank you for writing in The correct answer is D, corrections have been made. If you have any more observations please do well to call out our attention thanks.
Thank you for writing in. The CBT mode of examinations presents different questions to different candidates at the same time. That's also why we have more than the normal number of questions, which is 40. JAMB draws questions from a pool of questions in their database. Hence the reason we emphasize that you should practice as many questions as possible.
48 Is not D which is butane the right ans is Argon...you calculated butane with molacular mass instead of No of mole and you calculated others with no mole's
Thank u very much sir
Hope with all this information I will pass my jamb
It all depends on how well you have practiced towards your exams, we believe in you and you definitely need to believe in yourself too.
Very detailed explanation. Thank you
Glad it was helpful! enjoy.
Nice really works
Thank you so much sir
So nice of you, enjoy.
Nice one 👌
Thanks for watching.

7 moles of Ar contains 4.21 * 10^23 atoms
Therefore, option A contains the least number of atoms
Kindly indicate the question number.

@@MyschoolNigeria that means the total time should be 9000 but I didn't see such in your calculation
We didn't show all because of time.

From my research,I found out that jamb chemistry questions are usually 40 in total,but please why is it up to 50

Welcome.
48 Is not D which is butane the right ans is Argon...you calculated butane with molacular mass instead of No of mole and you calculated others with no mole's
Option D is Argon not butane.
@@MyschoolNigeria yes I made mistake the right and is butane it has lowest not of mole..
Alright, the question is about number of atoms not mole, if it were to be mole then butane is correct.
