What is the rate constant when 2.00 g plutonium-239 produces 4.69E9 beta particl

What is the rate constant when 2.00 g plutonium-239 produces 4.69E9 beta particles/min?

ok i think im a little confused because of how easy it might be...is the answer just 4.69E9?

Possibly. But you need units as well

Or maybe the 4.69e9 could indicate how much of the plutonium is decaying?
So perhaps you could figure out how much plutonium is left after X minutes by subtracting moles of beta particles from moles of Pu, plug everything into the first order equation and solve for k.
