I love how you have such a good plan and format for videos..... It lets you just crank them out, your channel is one of the best channels focusing on education
Good explanation....all due to a good vocalization speed...which in turn allows to assimilate the information...plus you kept it simple as it should be
1:44 . How individual atoms(ions) of the compound have the same M as the whole compound NaCl. For example 10g of NaCl converted to M is 0.171 M how then both Na and Cl ions have same 0.171M in that compound, Should it be 0.0855M for each atom(ion) . Can someone explain ?
As a student I remember always having problems with the notion that the molar mass of the compound on one side of the equation resulted in two ions potentially have the same molar mass...never made sense to me from an algebraic point of view, especially since everything was always a percentage and balanced. Always seemed to me that Na had to have 22.99/58.44 of the molar mass and Chlorine had to have 35.45/58.44 of the molar mass. Then suddenly two ions could have twice the molar mass...never added up. Only when you broke it back up into their mass did you realize there was 10 grams of NaCl on one side of the equation disassociated into 6 grams of chlorine and 4 grams of sodium. It might be smart to show mass breakdown as it correlates to molar mass results to show that they are indeed balanced.
thank you so much for this awesome explanation . so how do i go about when dealing with complex compounds ? for example im given 0.56M of NaSO4.6H2O and i have to find the concentration of Nickel
Sir can you teach how to count fertilizer such as calcium nitrate, potassium nitrate, phosphoric for example calcium nitrate 16kg,potassium nitrate 11kg,mkp2.5kg,mgs5kg mixed well in separate tank how to calculate cation and anion. Pls tq
Professor dave here is a question in physics as i didnt understand your other video A system consists of electrons and protons only.It contains 150 electrons and has a total charge of +22e.What is the mass of the system
well if it has a +22 charge then there are 22 more protons than electrons, so 172 protons, which each have a mass of 1 amu, and electrons are negligible, so 172 amu is the answer. what a weird question!

Absolutely , I love it
ive been struggling with concentration for so long, thank you so much for making such a good explaination!!

Thank you so much! Simple and straightforward
Expert presentation as always
👌 Very good my favourite teacher
Got exams on this in two days thanks
Clear concise explanation. Thank you!

Well one formula unit produces one of each ion.
@@ProfessorDaveExplains Wow Thx really fast reaply XD
This has helped me tremendously, thank you so much for all of your wonderful videos! You're a great teacher
10 hours before that quiz gets started.
me rn
@@kyle7413 good luck !
MY TEACHER DIDNT TEACH US THIS AND PUT IT ON THE TEST?!?!??!?!
Thanks for ur help

He read my chemistry exercise and came here
Perfect explanation
Thank you so much this lesson has helped me a lot!
thank you so much for this awesome explanation .
so how do i go about when dealing with complex compounds ? for example im given 0.56M of NaSO4.6H2O and i have to find the concentration of Nickel
There's no nickel in this compound.
well explained 👍👍

Wow this video would of been great LAST WEEK 😂😂😂😂😩😩😩
thank you so much
Great video! Keep up the good work! Definitely subscribed
Hi. Could u pls tell me how can i get mg ionic concentration in Mgcl^2.6h20 1534 gm in 3.5 liter???
Thanks
Thank you very much,Dave . Would the volume of NaCl be taken into account i.e (volume of water+volume of NaCl) if the mass of NaCl were 100 grams ?
nope, the ions just nestle into the empty spots in the water and they don't add any volume amazingly!
Professor Dave Explains ; the more you study chemistry, the more fascinating it’ll be . I appreciate your reply.
Thank youuuuuuu!!! A life saver god bless you
Thank you so much for the explanation:))
Love the video.❤
K3PO4 --> 3K+ + PO4 3- instead of 3K+ + PO4- (the phosphate charge...)
What if it’s two ions ? Is it still the the number per mol
How do you solve with only being given the moles of the solution and not the liters
Since there are 4 oxygens in sulphate am i not suppose to calculate for oxygen as well?
no the sulfate ion is covalent
@@ProfessorDaveExplains please explain a bit i dont understand ...
U dah best
You are great👌👌👌👌
But what if the Volume is not given and you are only given the Molarity of the ion and the ION itself.
thanks mann...
Thanks teacher I am Ethiopian citizens
8 hours before biggest exam
Thank you chemistry jesus
Great
okay soo what if my teacher doesnt give me the volume amount
Can you add Turkish subtitle PLEASE...
sorry dude i don't speak turkish!
@@ProfessorDaveExplains ok,not important. Your videos are really helpful. Thanks
I love you
FIRST COMMENT.....NICE VDEO SIR.....
you should have put in a mole ratio to show us how the ions/compounds are related. bad dave.
Please translate to arabic
sorry i don't speak arabic!
