Question

U1= 2110

U2= 2159

X1= 9855

X2= 4315

t (days) = 56

please find value of T1/2

Formula: (X1/X2)*(U2/U1)=2T1/2
Steps of the calculation:
1st step: calculate the left side of the
equation (all data are given in this pdf,
X1,X2,U1,U2 and t).
2nd step: take the logarithm of both sides,
do not forget logarithmic identities.
3rd step: calculate T1/2 in days and find the
isotope in the table: Half life
