The half-life of silicon-32 is 710 years. If 70 grams is present now, how much will be present in 200 years? (Round your answer
elena-s [515]

Answer:

57.7 grams

Explanation:

Given -

Half life of the silicon-32 = 710 years

Half life means the time period required by a radioactive element to reduce its mass by half.

Radioactive decay formula is

A = A_o*2^{\frac{-t}{h} }

Where

A represents the amount of radioactive element after time t years

A_0 represents the initial amount of radioactive element

t = time of decay

h = half-life of the substance

Substituting the given values in above equation, we get -

A = 70 * 2^{\frac{200}{710} \\

A = 57.7 grams
