What mass of `C^(14)` with `t_(1//2) = 5730` years has activity equal

1.	What mass of `C^(14)` with `t_(1//2) = 5730` years has activity equal to curie?
Answer» `-(dN)/(dt)=1 "curie"=3.7 xx 10^(10)` disintegrations per second `lambda=(0.693)/(5730xx365 xx24 xx3600)` `-(dN)/(dt)=lambda N " or " 3.7 xx10^(10)=(0.693)/(5730 xx365xx24xx3600)xxN` Or `N=9.65xx10^(21)` atoms Or amount of `.^(14)C=(14)/(6.023 xx10^(23)) xx9.65 xx10^(21)=0.2244g`
