Chemistry Tutorial 10.2b: Concentration - Parts Per Million And Percent By Mass Volume

[yakn1]

@markrosengarten your name sounds Jewish...

[MarkRosengarten]

@yakn1 Why are you so hung up on this? I'm an atheist. Jewish is a religion. I have no religion. Leave it alone.

[Jarrodmontelius]

@MarkRosengarten Lets face it, jewish is also a race. When a certain group of people bread with each other long enof they take on similar charictaristics, hence making a race of people. Its relevant because they happen to have the highest iq of any "race" and thats who we want to learn from!! lol jk. Nice video though, helped alot :)

[yakn1]

@markrosengarten are u Jewish?

[MarkRosengarten]

@yakn1 No, I am an atheist. I don't know why the question is relevant.

to be more fancy for the ppm, you can also use milligrams solute / kilograms solution

but grams solute / grams solution * 1,000,000 is probably faster

[MarkRosengarten]

@reyrey389 I teach in NY and the Reference Tables give the g/gX10e6 method so I stick with NYS standards for my lessons.  :)

omg. i wish you were my professor lol. the one i have currently goes too fast for my slow mind to comprehend. she's always here's a formula, and there's your problems. go do it. wtf -_- so yeah. thanks a lot for the clarification! :D <3

SICK PIGS hahaha it's actually SIG FIGS, short for significant figures

[Pikesterful]

ok, The second problem im getting an answer of 125000000. but the tutor here is getting 43000 ppm, ??,.. and whats he on about "two sick pigs, two sick pigs!"....???

Somwone please help

[lychee159]

@Pikesterful lol sick pigs actually means significant figures if im not wrong...

[Pikesterful]

@lychee159 - cheers for that pal!! x

[omoshiroi16]

thank you for being dedicated and spreading the wonders of chemistry is such a way few can do so. i guess it is your passion that allows you to do this :D

[microbialoreleaching]

I loooove your videos!! thanks sooo muchh!!

[lover4music94]

i have my end of year minister exam tomorrow and i never understood ppm.now i do and i have one less thing to worry about! THANKS!

[dhaccessories]

I've been getting "A's" on my chemistry tests ever since I found your videos. You make a difference in life. Thank you so much for all your help.

[glwalkergl]

Thank you. I am no longer confused on PPM.

[september1512]

thank u so so much.. this helped so much :)

[ChrisHellert]

I wish that guy was my chemistry-teacher.

mine just sucks compared to what I learned with this guy !!

Thanks for posting this, dummies like me need it so bad

[killerkitty777]

the answer to the 1st question is 0.45 ppm, not 4.5 according to my calculator...I am no math whiz, can't stand math honestly but look please:

0.0000450 / 100 x 1,000,000 = 0.45ppm

i tried in scientific notation too, same answer 0.45ppm

what do i get a different answer?

[MarkRosengarten]

@killerkitty777 Good call! I have fixed it. Thank you!

[R0kmyS0X]

@killerkitty777 Dude he has a text box saying 0.45 actually. I don't know if you posted this before he added that text box. But hope this helps, 1 year in the future lol, probably won't.
