A 1.55 g sample of an isotope has a half-life of 3.8 days. What mass of sample is left after 5.5 days?



Answer in the form x.yz g


Expert Answer

Step 1

Given that,

Initial amount of sample = 1.55g

Half life time = 3.8 days

Time = 5.5 days

Step 2

Now, you calculate the remaining amount of sample ofter 5.5 days

You know that n 1 N=N 2 Where, N=remaining amount N-initial amount 5.5 days n= 3.8 days n 1.45

Step 3
