Determine the Number of Polonium-210 Atoms in a Radioactive Sample

How can the number of polonium-210 atoms in a radioactive sample of Po-210 be determined?

The number of polonium-210 atoms in a radioactive sample of Po-210 can be determined using the sample's mass and the atomic mass of polonium-210.

Explanation:

First, you need to know the mass of the sample in grams.
Next, find the atomic mass of polonium-210, which is approximately 210 atomic mass units (amu).
Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to determine the number of atoms in the sample.
To calculate the number of atoms, use this formula: (Sample mass in grams / Atomic mass of Po-210) x Avogadro's number.
In summary, to determine the number of polonium-210 atoms in a radioactive sample of Po-210, you need the sample mass, the atomic mass of polonium-210, and Avogadro's number. Use the formula above to calculate the number of atoms in the sample.
