. A certain nuclide has a half-life of 45 years. After 225 years. 4.00 g remains. What was the original mass of the nuclide sample?
Interpretation:
Interpret the original mass of sample if the half life is 45 yr and after 225 yr 4 g left.
Concept Introduction:
Half life is the measurement of time required for the conversion of half of the reactant to product and can be indicated as t1 / 2.
A reactant reacts to produce product in particular duration of time whereas if time to be recorded for the completion of half of the reaction then it gets denoted by t1 / 2.
For determining the amount of sample remain after 45 yr.
Where, N is concentration of sample left = 4 g
N0 is original concentration of sample.
T h is half life = 45 yr
