Consider a pure sample of a radioactive isotope with a mass number of 46. If the sample has mass of 25.0 micrograms and the isotope has a half-life of 8.50x106 years, determine the decay rate for the sample. Give your answer in decays/secondand with 3 significant figures. Please show your work! I would like to understand the process.
Thank you!

As we know
T0.5 = 0.693 / lemda
and
R = (lemda) N
where
T0.5 = half life
lemda = disintegration const.
R = decay rate
N = total no. of nuclei in the sample

The nucleus of the polonium isotope 214Po (mass 214 u ) is radioactive and decays by emitting an alpha particle (a helium nucleus with mass 4 u). Laboratory experiments measure the speed of the alpha particle to be 1.76×107 m/s.Assuming the polonium nucleus was initially at rest, what is the recoil speed of the nucleus that remains after the decay?Express your answer with the appropriate units.
