If one starts with one curie of radioactive substance `(T_(1//2) = 12 hrs)` the activity left after a period of `1` week will be about

If one starts with 1 curie of radioactive substance (t_(1//2) = 12 h) , the activity left after a period of 1 week will be about

If one starts with 1 Curie (Ci) of radioactive substance (t_(1//2)=15 hr) the activity left after a periof of two weeks will be about 0.02x muCi . Find the value of x .

If one starts with 1 Curie (Ci) of radioactive substance (t_(1//2)=15 hr) the activity left after a periof of two weeks will be about 0.02x muCi . Find the value of x .

What percentage of a radioactive substance will left undecayed after four half-life periods?

If 5g pf a radioactive substanc ehas t_(1//2) = 12hr, 20g of the same substance will have a t_(1//2) equal to:

Starting with 10 g of a radioactive substance 0.1 gis left after 10 days. The rate constant for the decay is:

The half life period of a radioactive substance is 10 hours. How much will be left after 4 hours in 1g atom sample ?

A radioactive substance has t_(1//2) 60 minutes. After 3 hrs, what percentage of radioactive substance will remain ?
