Chemistry Tutorial 10.2a: Concentration - Molarity

[ohhyesbabyohhyes]

I just realized you have your watch on the right hand... maybe it's because i was CONCENTRATING so much on the video.

P.S very helpful video.

[yashoesandsox1]

I always thought we could abbreviate moles with a lower case n?

[MarkRosengarten]

@yashoesandsox1 That's the algebraic symbol for moles as a variable in an equation. It's also used to denote principal energy levels in quantum mechanics. The actual unit abbreviation is mol.

THANK YOU!!!

[WFLone]

great video it help me tons thanks.

[Legendaryjujitsumast]

I signed in to my youtube account, just to say thanks.. so thanks, if I would've been shown this visually in the first place.. it would've saved about 4 hours of frustration and confusion

[SUGGAMAMI9]

What is the molarity of H+ in an aqueous solution that is 0.31M HClO4?

[hot49gal]

Thank you for the help on molarity. It really helps my problem.

[cthougthz]

It's not fair, I wish you could replace my professor.

[gilangandikac]

I wish you were my teacher, you're amazing!

[zied1987able]

[imsochic]

amazing

[JoshyB94]

This guy is a great teacher! My teacher sucks and this video will for sure help me in my honors chem class!!!!

[alberiostar]

Without you, I would be failing chemistry. Thank you so much man.

[carlosp120]

Thanks a lot for this video, I have a chem exam tomorrow and I was having trouble with this kind of problems. You saved me!

[kshantanu1993]

HE TEACHES WAY BETTER THAN MY BLOODY CHEMISTRY(LOSER) TEACHER

[DOTTERSSDDANDTKD]

Mark, Thanks so much for your awesome teaching instruction. You make Chemistry fun and easy to learn. I give you a major part of the reason I have an A in my General Chemistry Class in College. Thanks and ps... Love the Cat videos too.

[itzfammibabee]

your amazing. i've had 3 teacher explain that to me...& i didnt understand till now.

[ssj7warrior]

Do you have any videos teaching Normality?

[HelloImQuin]

You have such a quirky, and fun personality. I enjoyed watching you throughout the molarity series videos. You have helped me sooooo much. Thankyou, thankyou, thankyou. I want you as a chemistry teacher so much!

[irishdizonabella]

thanks!!!!!!! GREAT HELP!! =D I was all left out in this topic but you made me understand it in just 9min!! I wonder why I cant get it from my prof in two hours in our class >XD

[braebrae20]

thank you excitable sir

8D

chuuu are quite helpful

[MissCarnivale]

I'm so freaking thankful for you putting up this video, cause frankly my chem honors class is kinda sorta a living hell for me.

[OnoffonStyler]

I love you!!! 

[gmasterswim]

I CANT EVEN TELL YOU HOW MUCH YOU'VE JUST HELPED ME! thank you!!

[olgakhumlo]

I have started to love chemistry

[ACTIVEDEVICE]

This guy is awesome!

[ssj7warrior]

You could make 180mL of what molar with 30mL of 4M?

[ssj7warrior]

@ssj7warrior I think I figured it out. 4*30/180=.67M

[MarkRosengarten]

@ssj7warrior Please give me the formulas of the acid and base in question. This isn't enough information to go on.

[ssj7warrior]

@MarkRosengarten That is all my book gave me, no lie. But I did figure it out. I got 4M*30mL/180mL=.067M. My book just gives the uestion and answer, I have to show how to solve the problem.

[MarkRosengarten]

@ssj7warrior They didn't give the formulas of the acid (like HCl) or the formula of the base (like NaOH)? Or even identify which was the acid or base? Not a textbook I'd ever use.  :) Good answer, though!

[ssj7warrior]

@MarkRosengarten In some problems they will give the compound. The book is called " Laboratory Mathematics: Medical and Biological Applications Fifth Edition" By Joe Bill Campbell and June Mundy Campbell, page 163, problem number 176. I don't know if you have the book or have access to the book but there is where it is, lol.

[dhaccessories]

I love your videos. You are the best teacher I've ever come across. How can we watch all your chemistry videos. I've arleady subscribe but everytime I click on your name, it won't let me because it keep saying the playlist is private. I wish I can watch all your chemistry videos. You are sooooo good at explaining things. Thank you so much for having these videos.

[EMOTIONZ80]

THIS IS SOO HELPFUL . U SOUND LIKE UR SPEAKIN MY "LINGO" :) THANK U SO SO SO MUCH

[redhed1967]

Thank you for this video. It helped a great deal. Now can you do a video using these problems as examples?

1. Normal saline solution is 0.9% NaCl. What is the molarity of normal saline?

2. Convert 500 mg/dl of glucose to moles per liter.

My professor is smart but likes to do the longest math you can do and it seems you have found a way to make it more simple. Thanks so much and look forward to viewing more videos.

[luvmabella]

THANK YOU SO MUCH FOR THIS WONDERFULL VIDEO YOU JUST MADE MY LIFE AND CHEMISTRY SO MUCH EASIER FOR ME........
