The half life of Cl is 9.5 x 10(exponent 12)s. How many atoms of Cl are present in a sample with an activity of 1.5 x 10(exponent 9) atoms/s
a. 2.1 x 10(exponent 22) atoms
b. 6.3 x 10(exponent 3) atoms
c. 4.9 x 10(exponent negative 23) atoms
d. 1.4 x 10(exponent 22) atoms
e. 7.0 x 10(exponent 23) atoms
Half life t_1/2 = 9.5 x 10^12 s
means, in this time, the radioactive material will have reduced to half its original ...
The solution explains each step and provides all mathematical steps.
Working with half life of a radioactive material
Polonium-210 has a half life of 140 days
If a sample has a mass of 200 mg find a function describing the mass that remains after t days
When will the mass be reduced to 10 mg?View Full Posting Details
