How many moles of mercury are 4.000 x 1022 atoms of mercury?

0.06642 moles of mercury

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

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry

i have no clue hope you find the answer
