Consider the daughter of radon 222 through alpha decay a, Ask an Expert

Academics

Consider the daughter of radon 222 through alpha decay. A sample, which initially contained 10 moles of this daughter particle, had 1.08999 kg left after 1.55 minutes.

a) calculate the atomic mass of that isotope of Po.

b) The Po would also undergo alpha decays.

Calculate the average KE of the alpha particles if the Po was initially at rest
