Finding Grams and Liters Using Molarity - Final Exam Review

[@ramankalam4224]

Till now I didn't had a favorite teacher but after listening to ur lecture ur my favorite teacher😍

[@frankigg1663]

Tip for the exam guys: If you watching the a question for 5 minutes, wake up because your sleeping 😂

[@R369B]

You have kept me from giving up on chemistry. Thank You!

[@partyovone9588]

I've found all your videos super helpful and clear thus far but this one really started confusing me so I had to stop it. Might've been the extra step you put in with mL -> L as I always found it simple enough to do in your head or off to the side and switching the division symbol to multiples. It's probably just me and getting confused easily cuz I went about answering those types of questions in a slightly different way. I really liked the analogy of the iced tea though, that makes what's what really easy to remember. Thank you for all your hard work and passion :)

I scored 178/180 in NEET MBBS entrance exam only because of u🙏Thanks a lot

I super late to being introduced to your videos but I just used your gas law videos for my exam last week and got a C. That’s huge for me since the time before I always got an F in that section. And you helped me to get that see by finally understand chem for the first time in i don’t know how long!! Now I’m using all your videos for my final this Monday and I actually feel prepared by using all your videos! You are a godsend to me in this subject, thanks so much and your amazing. Keep up the great videos and amazing fashion trends. Love it all 😁😍

[@carmenbisogno432]

Thank Thank YOU! your videos have helped me organize my scattered brain! My teacher is great but I love how colorful and organized your notes are, I love the step by step help. what my teacher shows me in 3 hours I learn in less than an hour with you!!!!

[@Tinykittens1]

My mom really loves your video, that you're amazing!

[@bryannabustamante7440]

Watching this to prepare for my ACS final this Monday!

[@liselibarringham988]

Your channel is amazing!!! I can't thank you enough.

[@haileynelson6140]

tysm for thiss, i couldn't understandthis for 9 months and now I get it :D

[@sugataffy]

Thank you!! My first exam I got a 78... after watching you video my second exam was a94! Thank you thank you for taking time to make videos! Please do more on molarity:)

[@ramankalam4224]

Its because of u I'm in love with chemistry thanks a lot 😘 And I love u to Mam💖

[@jessicawinslet684]

hmm i don't get it .. my question says how many grams are required to prepare 800 mls of a 16 g/L ... -- this makes no sense

[@alyssarichmond908]

youre actually the only reason im passing chem

Hi Melissa, I’m a new subscriber. I was hoping you could do a video that will help me reconcile AMU and grams/mole. I understand the atomic mass on the periodic table indicates the grams for 1x mole of atoms for a given element. I also know we can calculate the ‘weight’ of an Atomic Mass Unit (AMU) by dividing the atomic mass indicated on the periodic table by Avogadro’s number, then again by the atomic number to get the weight of a single AMU in grams. So why does it seem we use AMU and g/mol interchangeably? And how exactly did Avogadro know there were 6.022x10ˆ23 atoms per mole? Thanks and keep up the great work!

I wish i would've found this channel before having to study for my final exam

[@frankigg1663]

I ready took my final, thanks for helping !!! 😁 I think I got 3 out of 5 in the exam😂😂😂

[@ibrahimissaissa6627]

Thanks Melissa

[@melissamaribel]

You're welcome!

[@kylapatricezabala7171]

How many grams of K2SO4 (MW = 174.0 g/mol) are contained in 50.0 mL of 0.200 N solution? is N different with the M? or I can still solve with the same method mentioned on your lecture? If not, how will I solve this? Thankyou I hope you'll notice me

[@allthatmakeupALY]

So I found this really hard to follow personally. What helped me is first by getting the mass of glucose (180.16) you will need that later. You find that by doing the empirical formula and just adding everything together. (c6h1206= 6X12.011(carbon) 12X1.008 (hydrogen) and 6X15.999(oxygen)... once you get that you just plus in the numbers. My question was: What is the mass (in g) of the solute in L of glucose, CHO?.... you do 0.545L multiply by (0.58M/1L) times (180.16/1mol) and that's how you get your answer.

[@jiannerose]

What if I am given density (g/ml) instead of volume (ml) ?

[@dishwasherdetergent6144]

I'm confused. How did you get 14.9 grams KCL???? I multiplied everything on top and it gave me 14,910.

[@JorgeGonzalez-yc3de]

never known how much water to add specifically to get the solution total, regardless what the vase says

[@audreyphung7596]

thank you thank you thank you

[@melissamaribel]

You're very welcome!

Hi mam I'm from India I'm from very poor back ground but I love to read and now I'm willing to buy ur all book but it is very costly its my dads one month salary so sorry I'm not able to buy it😭

[@melissamaribel]

That's why I have these videos on KZbin for free so everyone can learn no matter where they are from. I have 2 more videos on molarity that can also help you learn. Video 1: kzbin.info/www/bejne/poexnZtvbquKi9E Video 2: kzbin.info/www/bejne/in3UaGyhgZ6Hj9U

Melissa Maribel youtube certainly comes with a territory. Many funny comments. Although you have helped me prepare for my next exam in my college chemistry class!
