There are as many notes as number of oxygen atoms in 24.8 gm Na_(2)S_(2)O_(3).5H_(2)O (Mw = 248). A note counting machine counts 48 milion notes per day. Number of days taken to count these notes is

There are as many notes as number of oxygen atoms in 24.8 gm Na_(2)S_(

1.	There are as many notes as number of oxygen atoms in 24.8 gm Na_(2)S_(2)O_(3).5H_(2)O (Mw = 248). A note counting machine counts 48 milion notes per day. Number of days taken to count these notes is
Answer» `10^(17)` `10^(16)` `10^(10)` `10^(12)` SOLUTION :No.of O-atoms = `(24.8)/(248)xxN_(0)XX8` `48xx10^(6)rarr1" day"` `0.8xx6xx10^(23)rarr?=10^(16)`
