I am still reading these half lifes in book so confused

3 half lifes meaning there will be an 8th of the atoms left, can you go from mass to atoms?

I just got that as you did

No i would calculate the atoms total and then divide them by 3/4 and those would be the ones that are N

I'm sorry I just don't understand with the 200 gram sample

i have done it before but would have to go back into book to reread again

\[200g(\frac{1 mole c}{12.01g c})\frac{6.022x10^23 c atom}{1 mole c})\] that will get you atoms,

Does that look like anything you have ever done?

not that complex

1.00x10^25 is the total (I think i'm using a jankie calculator) now just multiply that number by .875 and that will be the number of nitrogen

zbay thank you I guess some people just don't understand that it just doesn't click for me. Another guy was very mean like I am some dumbass.

No chemistry is a ball buster, it takes a lot of practice and everything builds on previous knowledge. If you keep pluging away at it i'm sure you will get a handle on this subject. Good luck and keep asking questions!

in 3 halflifes, 200g carbon14 will decay to 1005025g, so taking that carbon14 decays to nitrogen14, 175 g is produced or using the halflife formula, amount of nitrogen14 produced = 200  200*0.5^(17190/5730) = 175 g

Thats a much easier way to do it, It can be calculated the way i explained it sorry if i added to the confusion
