Final answer:
To find the number of moles equivalent to 7.01 × 10²¹ atoms of Hg, divide the number of atoms by Avogadro's number. The calculation yields the number of moles for mercury. Adjustments to Avogadro's number are not needed in this standard mole unit calculation.
Step-by-step explanation:
The number of moles equivalent to 7.01 × 10²¹ atoms of Hg (mercury) can be found by using Avogadro's number, which is approximately 6.02 × 10²³ atoms per mole. To convert atoms to moles, divide the number of atoms by Avogadro's number:
Moles of Hg = (7.01 × 10²¹ atoms Hg) / (6.02 × 10²³ atoms/mol)
After performing the division, you will get the number of moles for mercury.
If we were to use the American system and measure amounts in pound moles, Avogadro's number would be scaled by a factor, but in this instance, we are working with the standard mole unit.
