Using the equation for decay, calculate the amount left of a radioactive sample amount N0 if the decay constant is 0.00125 seconds and the time is 180 seconds? (Hint: Your answer will not be a number. Instead, it will be a decimal or percent of the variable N0
The amount left of a radioactive sample amount N0 if the decay constant is 0.00125 seconds and the time is 180 seconds is 0.7999 N.
What is half-life?The time it takes for half of the original population of radioactive atoms to decay is called the half-life. The relationship between the half-life T1/2 and the decay constant is given by T1/2 = 0.693/λ.
N=N0e−λtgiven λ = 0.00125 secondst = 180 secondsNow putting values.N=N0e−λt = 0.799N= 0.7999.Read more about the radioactive :
