1.	The half-life of a radioactive element is 10 hours. How much will be left after 4 hours in 1 g atom sampleA. `45.6 xx 10^(23)` atomsB. `4.56 xx 10^(23)` atomsC. `4.56 xx 10^(24)` atomsD. `4.56 xx 10^(25)` atoms
Answer» Correct Answer - B `N_(t) = N_(0) ((1)/(2))^(n) n = 4//10` `:. N_(t) = 6.022 xx 10^(23) xx ((1)/(2))^(-.4) = 4.56 xx 10^(23)`
