Plutonium-240 decays according to the parent function
q(t)=q0e^-kt
where q represents the quantity remaining after t years and k is the decay constant,0. long will it take 27 grams of plutonium-240 to decay to 9 grams?

Time taken = 9987.38 years

Step-by-step explanation:

We have plutonium-240 decays according to the parent function

k is the decay constant,0.00011

k = 0.00011

We need to find how long will it take 27 grams of plutonium-240 to decay to 9 grams.

Q(t) = 9 g

Q₀ = 27 g

Substituting

Time taken = 9987.38 years

9990
