How did you get the 1.75 moles you never explained that part

[@sciencemadeeasier7100]

you're basically, instead of saying, for every 4 moles of NH3 you need 7 Moles of O2. your dividing 4 by 4 to make it 1 and whatever you do to one side of the equation you have to do the other, so you divide 7 by 4 aswell to get 1.75. therefore for every 1 mole of NH3 you will need 1.75 Moles of O2

[@ej4458]

@@sciencemadeeasier7100 but why by 4? why not by 7?

[@bakhshizulfiqarmanzur8988]

@@ej4458 I think it's because if you divide by 7, you would get a recurring decimal if you divided by 7, thus making your life harder for no reason

[@charlierichardson8778]

@@ej4458 ​ @Bakhshi Zulfiqar Manzur you are dividing 7 by 4 so that you can find out how many moles of O2 reacts with 1 mole of NH3

[@zainpunjwani470]

@blip trip in math generally, you want to get to 1 as your least common factor, so to get 7:4 is the same as 1.75:1 since 7/4=1.75, and 4/4=1. Hope this helps! :D

I'm a senior in engineering and i needed to review how to do this stuff. You made this video short, straightforward, and easy to understand. thank you

[@sciencemadeeasier7100]

Thank you very much Alex, glad I could be of assistance.Good luck, finish strong. I have a good friend in his junior year now..shit looks nasty

[@ItsAkra]

I have watched at LEAST a dozen L.R. vids, trying to understand this (including all the best known Chem people on here) and this is THE ONLY ONE I GET. Thank god I get it now!

[@sciencemadeeasier7100]

+Alexandra “North Star” Wilson Thank you so much! Thats exactly what I thought before I made my chemistry tutorials.. I couldn't find a good video online to teach me so I made my own videos to basically teach myself but others find them very useful :) Glad I could be of assistance and thank you for the compliment!

[@shanthinarayan7019]

Yeah

[@thembiemadlophe2618]

Simple, straight to the point videos like this are hard to find these days on here, thank you.

[@sarahshaban906]

this makes so much sense now! my new teacher just assumed everyone knew how to find limiting reagent but some of us students need to be reminded. thank you for this video!

[@juanvalencia9378]

Great video! I looked at 3-4 other sources and your explanation was by far the best. Keep up the good work!

[@liamphillips9027]

thank you so much man i've been stuck on this for a few hours now and i finally get it, i've watched so many other videos but this video finally made it click! Thank you!!!!!

thanks man, i did so many of these wrong as I mixed up how many moles needed with how many you actually have - this was a very clear explanation

[@LeyahStorm]

Thanks for this. I've been super confused about Stoichiometry and I've watched other videos, even with a food analogy, but this one made the most sense. Cheers!

Ive been stressing all week because my teacher sucks at teaching and I have to resort to KZbin as a replacement for my teacher. I finally found a video that made finding limiting reactants simple that also showed how you find the actual mole ratios. Thank you!

Saved me man, ily

[@AkashKumar-wm6vv]

how do u get 1.75??

[@sciencemadeeasier7100]

+Akash Kumar 4 moles of NH3 require 7 moles 02. Therefore, Each mole of NH3 requires 7/4 of a mole of O2. Understand?

[@onalennamoeti4231]

+ScienceMade Easier no

[@amiracampbell5973]

Onalenna Moeti So basically it's, So 4/4 = 1 So 7/4 = 1.75

[@sydneym3251]

Onalenna Moeti you have 4 mol NH3 and 7 mol O2. So when you take one mol NH3, you divided the original 4 mol NH3 by 4. (4/4 =1) So to keep the ratio the same, you also need to divide the original 7 mol O2 by 4 also (7/4 =1.75) . So that’s where the 7/4 mol O2 comes from.

[@TheDrewster1123]

you're basically, instead of saying, for every 4 moles of NH3 you need 7 Moles of O2. your dividing 4 by 4 to make it 1 and whatever you do to one side of the equation you have to do the other, so you divide 7 by 4 aswell to get 1.75. therefore for every 1 mole of NH3 you will need 1.75 Moles of O2

[@NIKKI-xu7qb]

u are so so good. do u have video on theoretical yield calculation

[@ZacHHackable]

its simple what the problem gave you divided by what the stoich equation gave you

[@lucyw5684]

Why do you do moles of NH3 x moles of O2 needed? I thought you did 8.06/2.58 to get the ratio then compare it to the ratio from the formula to see which one's in excess

[@gageoutlaw3824]

Thank you

[@OGtrushalpatel]

That was surprisingly easy...
