Question

How many moles of mercury, Hg, contain 5.41 x 10²⁴ atoms?

Answer 1

To determine the number of moles containing 5.41 x 10²⁴ atoms of mercury, divide the number of atoms by Avogadro's number, 6.022 x 10²⁳ atoms per mole.

Step-by-step explanation:

The question 'How many moles of mercury, Hg, contain 5.41 x 10²⁴ atoms?' pertains to the concept of molar calculations in chemistry. To answer this, we use Avogadro's number which defines the number of entities in one mole of a substance. Avogadro's number is 6.022 x 10²⁳ entities per mole.

To find the number of moles of mercury from the given number of atoms, we divide the number of atoms by Avogadro's number:

Number of moles = Number of atoms / Avogadro's number
Number of moles of Hg = 5.41 x 10²⁴ atoms / 6.022 x 10²⁳ atoms/mol

This calculation will give us the number of moles of mercury that contain 5.41 x 10²⁴ atoms.
