In the gold foil experiment of Geiger and Marsden, that paved the way for Rutherford's model of an atom, $\sim 1.00 \%$ of the a-particles were found to deflect at angles $>50^{\circ}$. If one mole of a-particles were bombarded on the gold deflect at angles foil, compute the number of a-particles that would less than $50^{\circ}$.
