Final answer:
To find the number of moles represented by 2.95 * 10^23 Hg atoms, you divide the number of atoms by Avogadro's number, resulting in approximately 0.49 moles of Hg.
Step-by-step explanation:
The question 'What is 2.95 * 10^23 Hg atoms?' relates to Avogadro's number and the conversion of atoms to moles in Chemistry. To convert atoms to moles, you need the relationship provided by Avogadro's number, which is 6.02 × 10^23 atoms/mole. Since 2.95 × 10^23 is less than Avogadro's number, we understand that we have less than one mole of Hg (mercury) atoms. To find the number of moles, you divide the number of atoms by Avogadro's number.
Number of moles = (2.95 × 10^23 atoms Hg) / (6.02 × 10^23 atoms/mole) = approximately 0.49 moles of Hg.
