The half-life (t_half) is the time required for half of the radioactive nuclei in a sample to decay. For uranium-237, the half-life is given as 2.5×105 years. 2. Determine the Fraction Remaining: We are looking for the time when the remaining amount of uranium-237 is 25% of the...
Step 2: Calculate the Decay Constant (λ)The decay constant (λ) is given by the formula:λ=ln(2)ThalfSubstituting the values:λ=0.69310 hours=0.0693 hours−1 Step 3: Calculate the Remaining Mass After 2 HoursUsing the formula for radioactive decay:m(t)=m0⋅e−λtSubstituting the ...
To solve the problem of finding the time taken between 40% decay and 85% decay of a radioactive substance with a half-life of 30 minutes, we can follow these steps:Step 1: Understand the Decay Process The half-life of a radioac
