The Mole

[@sooraz9081]

You dont know how much i appreciate your videos you are actually a life saver

[@user-lb4ju8gu4h]

we need to memorize all the equations/fomular right?

[@jamesdoyle9880]

Thank you very much this is very student friendly and helps me to now understand. But will putting *10^-3 be seen to be correct on a gcse mark scheme or will you have to covert?

[@AlleryChemistry]

I would convert at GCSE.

[@omranhasanali9343]

THANKS SIR!!

[@thegeniusofslaughter7155]

What I don’t understand is the moles of gas, because, the equation I learned was: moles= concentration * volume. Could you please tell me the difference and if what I learned is correct and which one should I use/is better. And any additional info I should know about it. Thank you and I hope you respond. Bye

[@Think-Deutsch]

The one he put is the correct one. I believe you've mistaken the solution equation for the gas one :)

[@mrmpullen1637]

moles= concentration * volume is used for solutions. When using gases you use n =v/24. Just like for solids you normally use n=m/Mr

[@coolpuppet8011]

That’s for solution not gas , gas is Pv= nRT

Are your videos also compatible with Edexcel?

[@AlleryChemistry]

Yes. Here is the full playlist for Edexcel. kzbin.info/door/PtWS4fCi25YHw5SPGdPz0gplaylists?view=50&shelf_id=4&sort=dd

[@MohammadKhan-ls9qw]

Thanks a lot! Can you also solve more Edexcel papers for AS Levels since I struggle with the questions sometimes. I would be very thankful since it would help me greatly.

Why are people I find online a million times better than my teachers

[@trishajohnson6199]

Do you teach physic also?

[@AlleryChemistry]

Nope. Just Chemistry at A Level.

[@trishajohnson6199]

Okay thanks
