1. Find the molar mass of plutonium:
* The molar mass of plutonium (Pu) is approximately 244 g/mol. This means that one mole of plutonium atoms weighs 244 grams.
2. Convert grams to moles:
* Divide the mass of plutonium (1 gram) by its molar mass:
1 g / 244 g/mol = 0.00410 mol
3. Use Avogadro's number:
* Avogadro's number tells us the number of atoms in one mole of any substance: 6.022 x 10^23 atoms/mol
* Multiply the number of moles by Avogadro's number:
0.00410 mol * 6.022 x 10^23 atoms/mol = 2.47 x 10^21 atoms
Therefore, there are approximately 2.47 x 10^21 atoms in 1 gram of plutonium.
