Best ResponseYou've already chosen the best response.23 half lifes meaning there will be an 8th of the atoms left, can you go from mass to atoms?

Best ResponseYou've already chosen the best response.2No i would calculate the atoms total and then divide them by 3/4 and those would be the ones that are N

Best ResponseYou've already chosen the best response.2\[200g(\frac{1 mole c}{12.01g c})\frac{6.022x10^23 c atom}{1 mole c})\] that will get you atoms,

Best ResponseYou've already chosen the best response.21.00x10^25 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

Best ResponseYou've already chosen the best response.2No 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!

Best ResponseYou've already chosen the best response.0in 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

Best ResponseYou've already chosen the best response.2Thats a much easier way to do it, It can be calculated the way i explained it sorry if i added to the confusion
