Radioactive Decay Calculations Practice Problem

Here, we'll work through a calculation involving radioactive decay. This type of problem involves variables including nuclear or radioactive half-life, decay constant (k), time elapsed (t), as well as natural log (ln) functions, and the number e. Questions of this type are commonly found involving unstable isotopes and radioactive dating. In this particularly problem, we are given a starting amount (in grams) of Radon-222, and we must determine how many grams will remain after a specific length of time.

We have missed you a lot. Could you teach us organic chemistry as well which most chemistry students stuck. I admire you a lot. You’re the best teacher I have ever seen.

This is kinda out of context but i just want to express my gratitude to Tyler cuz if it's not for his videos I would not have this sweet sweet A+ result on chemistry, and i used to fail chemistry every single time.. Thank youuu Tyler from the bottom of my heart it is ❤

I finished my Geology class about a couple weeks ago. It's interesting that we did a very simple version of this topic and I didn't know there could be much more complex questions from it! I'll be sure to come back to this video once I get back to this in a future Chemistry class. Thank you Mr. DeWitt!

Thanks..please continue this series.. i love your way of explaining things..
I was in 8th grade when i first watched your video.. I've now graduated highschool and prepping for medschool entrance exam.. thanks..love your way of explaining

[DerpyMemeLord]

Even though my exams have finished and I'm not choosing science for A level, I just wanted to thank you for all the support you have given me and helped me. Best of luck for the future and I'll always stay subscribed to you.

Even if I don't need to learn the concept I still watch your videos cuz I just love your teaching style

[eieilannaung]

Watching yours lessons from Myanmar🇲🇲🇲🇲.
I really like yours videos.I am a Chemistry student and it helped me a lot.Please keep working.✌✌✌✌✌🙏🙏

[murugans]

I am really happy to see ur video... i learn lot of things... Thank u sir... i am waiting for lot of videos in future

[sanchitwadehra]

Love from India I have learned a lot from you in my 9th and 10th grade now I am going to give my JEE exam in a month

[mlaburbano]

honestly you are my chemistry safer! muchas gracias Tyler!
I just saw that you have new videos. those are great too! But for some reason I love the ones when you were using paper!
thank you again!

I missed this guy. I have completed mi highschool recently ND I stopped watching his videos. Anyway his videos are still outstanding. shout out to him!!

[kushagrasthana]

Keep up the good work 🔥
Love from India ❤️

[devansh]

This is amazing you help me a lot please keep uploading Videos

[AliHassan-hbbn]

Yeah, very recently. This is a lot of calculus. Well done

[mikefixac]

Beautiful. How many people would you run into before someone could do the math, even when given the initial formula? Also, I don't quite get 1/2 life. For example, when determining how old something is, I'm guessing to figure out 1/2 life, the scientist assumes full life was initiated at a certain time. I don't see how they get that date.

Please can you teach us atom modern theory
I'm finding it kinda difficult to understand

[dooman]

Is the rounding correct? 0.18145… I thought if you have 5 you round 4 to 5 which in turn leads to 0.182

[FireAlert]

I need to take another chem class so i can use this

[kamalmalik]

can you teach organic of 12 by your old paper method

[jax]

We wanna see your beautiful face Tyler!!
