In the gold foil experiment of Geiger and Marsden, that paved the way for Rutherford's model of an atom, `~ 1.00%` of the `alpha`-particles were found to deflect at angles `gt 50^(@)`. If one mole of `alpha`-particles were bombarded on the gold foil, compute the number of `alpha`-particles that would deflect at angles less than `50^(@)`.

Explanation

Percentage (%) of particular deflected at an angle more tht `50^(@)`=1%
Percentage (%) of `alpha` particles drfected at an angle less than `50^(@)` =100-1 =99%
Moles of `alpha`prarticles which bombarded the given gold foil =1 mol or 6.022 xx `10^(23)` particles
No of `alpha` particles deflected at an angle less than `50^(@) = (6.002xx10^(23)xx99)/(100)=5.96xx10^(23)`
