Answer 2

There are  0.6326 mole in Cu atom and 0.4397 mole in S atom.

What is mole?

A mole would be defined as the quantity of a material that includes precisely 6.02214076 X $10^{23}$ of the substance's elementary entities.

Calculation of mole of Cu

Given data:

Mass of Cu = 40.2 g

Molar mass of Cu = 63.546 u

Mole?

Mole can be determined by the formula:

Mole = mass / molar mass

Mole = 40.2 g / 63.546 u

Mole = 0.6326

Calculation of mole of S.

Given data:

Mass of S = 14.1 g

Molar mass of S = 32.065u

Mole = ?

Mole can be determined by the formula:

Mole = mass / molar mass

Mole = 14.1 g / 32.065u

Mole = 0.4397

Therefore, there are  0.6326 mole in Cu atom and 0.4397 mole in S atom.
