Prasenjeet,
The problem is : 49/(49000*1.660*10-27)=6.022*10^23
Use scientific notation & simplify:
49/(49*10^3 * 1.660 * 10^-27)=
1/(10^3 * 1.660 * 10^-27)
1/(1.660 * 10^-24) =
(1/1.660)*10^24 =
6.024 * 10^23
Note: The original problem has a most 2 significant digits (ie 49) so the answer should be reduced to 2 significant digits also:
6.0 * 10^23
