Answer #1

Here, the value given is the activity of the sample

The activity of a sample is the product of no of atoms and the decay constant of the atom.

The half life of 3 H is

The decay constant is given by

Thus, no of particles is given by

No of moles can be estimated by dividing this by the Avogadro number

NA = 6.022*1023

So,

Using the molar density = 3.016 g/mol

The mass of the sample

Helium (He, atomic weight 4 g mol-1) and argon (Ar, atomic weight 40 g mol-1) are both produced in the Earth’s interior and exhaled to the atmosphere. Helium is produced by radioactive decay of uranium and thorium; argon is produced by radioactive decay of potassium-40 (40K). Both helium and argon, being noble gases, are chemically and biologically inert and are negligibly soluble in the ocean. Present-day atmospheric mixing ratios of helium and argon are 5.2 ppmv and 9340 ppmv, respectively....
