The radioactive decay of a certain sample produced 846 disintegrations per minute. exactly 3.00 days later, the rate of decay was found to be 269 disintegrations per minute. calculate the half-life, in days, for the decay of this sample.

Explanation:

1. Calculate the decay constant

The integrated rate law for radioactive decay is 1

where

A₀ and A_t are the counts at t = 0 and t

k is the radioactive decay constant

2. Calculate the half-life

The half-life for decay is .

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
