1. Find the molar mass of mercury:
* The molar mass of mercury (Hg) is 200.59 g/mol. This means one mole of mercury weighs 200.59 grams.
2. Calculate the number of moles of mercury:
* Divide the given mass by the molar mass:
* Moles of Hg = (2.36 g) / (200.59 g/mol) = 0.01176 mol
3. Use Avogadro's number to find the number of atoms:
* Avogadro's number is 6.022 x 10^23 atoms/mol.
* Multiply the number of moles by Avogadro's number:
* Number of Hg atoms = (0.01176 mol) * (6.022 x 10^23 atoms/mol) = 7.08 x 10^21 atoms
Therefore, there are approximately 7.08 x 10^21 atoms in 2.36 g of mercury.
