It is known that 1g of .^(226)Ra emits 11.6 xx 10^(17) atoms of alpha – InterviewSolution

1.	It is known that 1g of .^(226)Ra emits 11.6 xx 10^(17) atoms of alpha per years. Given, the half life of .^(236)Ra to be 1600 years, compute the value of Avogadro's number.
Answer» SOLUTION :Rate `= lambda xx` number of ATOMS in one gram `= lambda xx ("Avogadro's number")/(226)`
