Problem based on radioactive decay

Reference no: EM13707175

Question- Radioactive Iodine-125 used for studies of thyroid functioning, has a rate constant for decay of 0.011/day. If you are given a dose of iodine-125 containing 1.6 x 1010 atoms, how many remain after 4.0 days? Assume first order process.

Anyone can tell me how to solve it step by step so that I will be able to understand what is going on?
