The half-life of cesium-137 is 30 years. Suppose we have a 170-mg sample. What is the rate of decay after 150 years? (Round your answer to three decimal places.)

5.313mg

Step-by-step explanation:

The half-life of cesium-137 is 30 years. Suppose we have a 170-mg sample. What is the rate of decay after 150 years? (Round your answer to three decimal places.)

Half life formula

= N(t) = No(1/2)^t/t½

N(t) = Amount after t years

No = Initial amount

t = time

t½ = half life

N(t) = 170 (1/2) ^150/30

N(t) = 170 × (1/2)^5

N(t) = 5.3125mg

Approximately the quantity left after t years = 5.313mg
