Answers: (2) 2.69g. Practice question (a)1 mole (b)9moles (c)0.1moles (d)1.37moles this has been an amazing TH-cam channel thank you sir for ur time and effort we appreciate 😊😊😊😊😅
Hey i am preparing for the medical admission test and you have been helping me tremendously! I finally understand those concepts 🎉 greeting from france ❤
@NurseBright 2Al yields 3H2 8.10 yields zgram of H Cross multiply to get = 12.15 mole of Hydrogen Mass = n x molar mass of Hydrogen= 12.15 x 1 = 12.15g of Hydrogen The other questions n of mole in sulphur of 32g of comp = 1mole NaOH 3dm cube of 3.0mol/dm = 9moles HCl are 50g of the comp= 1.37moles
2AL-------3H2 2moles------3moles 8.10-------xmole Therefore;x mole=3×8.10/2 =12.15mole Mass=n×M Mass of hydrogen=12.15×1 =12.15g Sir am I correct if not correct you can as well solve the correct for me please 🙏🙏

Ques 9=0.949mol/dm³
Thank you very much sir✨✨
Best chemistry teacher
❤️❤️❤️❤️
Anticipate More Video lessons
Thank you very much sir ❤
Thanks for explanation I got 0.688g of mass
I love your teaching so understandable,I always wish you are also teaching physics
I wasn't really seeing the board but your voice got me covered. You are making chemistry easier for me. Thank you
♥️💥♥️

Please Chinecherem how did u get 2.69g
Thanks for this sir
God bless Nurse bright
You are welcome 💥❤️💥

Hey i am preparing for the medical admission test and you have been helping me tremendously! I finally understand those concepts 🎉 greeting from france ❤
You are welcome ❤️❤️
Expect More Video lessons soon
Sir you are too Good. Fly high boss
Amen ❤️... Big thanks Help Share With Friends
I love this teaching ooo
Best❤
Thank you so much sir I understand this topic better all thanks you
God bless you 😊🙏
You are welcome . Keep sharing with friends
@NurseBright 2Al yields 3H2
8.10 yields zgram of H
Cross multiply to get
= 12.15 mole of Hydrogen
Mass = n x molar mass of Hydrogen= 12.15 x 1 = 12.15g of Hydrogen
The other questions
n of mole in sulphur of 32g of comp = 1mole
NaOH 3dm cube of 3.0mol/dm = 9moles
HCl are 50g of the comp= 1.37moles
Thanks a lot sir
thank you very much nurse bright
Love you so much you are the best
Thanks, so glad you have been impacted greatly by my video lesson. Keep sharing with others

Question 9: 0.948mol/dm³
Hi Mr Bright, u teach well
Keep it up, pls l have problem in my study
♥️♥️
Question
(a) 5.316
(b)9
Answers no9: 1.05g/mol
My answer for the last question is 0.9g
2AL-------3H2
2moles------3moles
8.10-------xmole
Therefore;x mole=3×8.10/2
=12.15mole
Mass=n×M
Mass of hydrogen=12.15×1
=12.15g
Sir am I correct if not correct you can as well solve the correct for me please 🙏🙏
The ans is 24. 4
@@EuchariaUgochiCould you please, explain how you got your 24.4?
Please how do we equate the reaction if the reaction is not given in the question.
How do we know when to convert from cm3 to dm3
You will Divide By 1000
The value in cm3 divide by 1000 to get a value in dm3.

Sir what is the cut off mark for nursing
280
Please i don't know how to solve question 2
Nurse Bright 💖
Practice Questions
A 1mol
B 9.0mol
C 2 mol
D 1mol
E 1.054mol/dm3
Very Correct
Pls I got 2.8 mol for d
Am I wrong
Pls if I am, can I see a solving of the correct one pls sir
How did you solve ur d?
1.05mol per dm cube
It is a much we divide the cm3 by 1000
Yes
❤
Sir why don't you teach physics😢
He's a nursing student, physics doesn't concern them

Nurse bright sir do you have a WhatsApp number where questions can be asked
Sir u from and are you Muslim or Christian
Rest, does this question relate to what he's teaching? Learn and leave religion apart
@prof.kingjerry5356 thank you
