Answer:
0.06642 moles of mercury
Step-by-step explanation:
Step 1: Given data
Moles of mercury: 4.000 × 10²² atoms
Step 2: Calculate the number of moles of mercury that correspond to 4.000 × 10²² atoms of mercury
To convert atoms to moles, we need to consider the Avogadro's number: there are 6.022 × 10²³ atoms of mercury per mole of mercury.
4.000 × 10²² atoms × (1 mol/6.022 × 10²³ atoms) = 0.06642 mol
