Chemistry | Stoichiometry | How to calculate percentage yield

[@dimphomashifane]

I hope you see my message... ii used to fail physics dismally in throughout then ii discovered you towards the finals ...I'm telling you my marks improved a lot... from failing it to getting a 62% on my statement yhoo .. it is an achievement for me knowing where I come from.. thank you so much sir ..because of you I'm in university studying Animal Science... May God keep on blessing you and keep on using you as his voice and hand in Jesus name...thanks a lot man

[@a.dria_na]

Congratulations 🎉

[@sandrachioma7909]

Thank you so much, I learnt a lot from you, even my friends to I told about you are improving, thank you sooo much

[@MlungisiNkosi]

Thank you Sandra

[@millicentmagaba2633]

You are really a blessing sir ... You are really helping.. thank you and God bless you ❤️

[@MlungisiNkosi]

Thank you 😊

[@josechauke856]

thank you, sir, like you explained so much better than the booklets you are amazing! like am watching this video at 00:40 am sleepy but still went through

[@inamcareennokwe4312]

Me watching this at night:👁👄👁

[@MlungisiNkosi]

Creepy 🤣

Thank you 😊

It really does help

[@carolkgwete]

This helped so much!! Thank you

[@MlungisiNkosi]

I'm so glad! Thank you for being part of the family

[@leslienkwonia1075]

Thanks a lot for this fantastic video, God bless you! : )

[@MlungisiNkosi]

You’re welcome

[@SandileGman18]

Thank you video was really helpful

[@MlungisiNkosi]

You’re most welcome 🤗

[@beyoncemakhubedu8453]

This really helped me a lot thank u

[@MlungisiNkosi]

I'm happy to hear that... Let's get those great results.

[@beyoncemakhubedu8453]

Do you have anything on limiting reagent calculations?

[@MlungisiNkosi]

@@beyoncemakhubedu8453 yes please keep checking in this Playlist on Stoichiometry.

[@maryam-pk4py]

thank you i understand it well

[@MlungisiNkosi]

You are welcome!

Hi sir, what if you given the number of moles. Do you use the 150 grams as actual yield. How would you find the theoretical yield, when only one mass is given?

[@miltonmutondofwamu]

Please briefly explain why the coficient in aluminum was not used to calculate number of moles

[@doaahezam9642]

Iron reacts with oxygen to form iron(III) oxide according to the chemical equation below. What is the theoretical yield of product when 5.00 grams of Fe react with excess O2? [Molar masses: Fe, 55.85 g/mol; O, 16.00g/mol] 4Fe(s) + 3O2(g) → 2Fe2O3(s) how can i solve this question?

[@MlungisiNkosi]

Please go and watch my Stoichiometry playlist and you give me the answer afterwards

[@innocentsbusiso9073]

Thanks you bhud mlungisi🥰

[@MlungisiNkosi]

Danko ntwana

[@azasouthafricanyoutubers5654]

Sir how do we know that aluminum is our limiting reagent?

[@MlungisiNkosi]

We will be told that or they will tell us that other substance it is reacting with is in excess

[@azasouthafricanyoutubers5654]

Thank you sir, pls do ideal gases when you have time 🙏

[@nelisiwelukhele485]

Are we always given a balanced equation in exam??

[@MlungisiNkosi]

For Grade 12, yes... I would however suggest that you learn how to balance chemical reaction as best practice

[@OleratoM21]

Thank you sir🙏

[@MlungisiNkosi]

You're welcome

[@nonhlenicolendlovu8923]

Greetings Sir.How do you know which element is the ideal or actual Yield?

[@MlungisiNkosi]

The actual yield is often given and the ideal one is what you get if you use up all your limiting reactant

[@moneuamber5948]

Can you please do a case where maybe you are given the percentage yield and maybe they ask for the mass or actual volume. Is there ever a case where they give you the percentage purity and then require you to find the value of when it was impure?

[@MlungisiNkosi]

Hi, The point is to empower you with enough content so that you’re ultimately answer those questions yourself. Come now, think a bit.

So sir knowing Which one is LIMITING REACTANT it is important

[@ayeshabibisulaiman9915]

Thank you.

[@MlungisiNkosi]

You're welcome

[@BlessingSelepe]

sir i do understand how we calculated but i need explanation of ideal and actual moles🙏🙏

[@sandilexaba750]

Dankie😊👏

[@MlungisiNkosi]

You're welcome

[@luckyzulu3048]

Can do u one on percentage purity

[@MlungisiNkosi]

It's done... I'll upload it tomorrow.

[@MlungisiNkosi]

As promised...

[@kgaogelo_G]

Sir do we calculate %yield the same way we calculate %purity?

[@MlungisiNkosi]

Yes. Did you understand this example?

[@kgaogelo_G]

@@MlungisiNkosi I definately did sir. I appreciate your work so much you really helped me when I had no idea of where to start when I got a question like this one❤

[@girlyphawe7825]

I want to cry because I'm watching this now,😭

[@showers8679]

Ok

Sho 😊

[@mickeythabile3993]

Thanks malume , all my anxiety is now gone 😭🙊🥹

[@MlungisiNkosi]

I’m happy to hear this

[@goldengirls9534]

Someone please locate me to the video where he was explaining how to balance equations I’ve been looking🥲

[@MlungisiNkosi]

I will do it just for you

[@SifisosethuDladla]

​@@MlungisiNkosi i also need it sir I'm struggling to understand how to balance equations
