The atomic mass of gold is 79g/mol
Therefore, 4540 grams will have
4540/79 = 57.46835
Therefore; 
 = 57.468 moles

To calculate moles , we divide mass of the substance given by the molar mass of the substance.

That can be mathematically represented as:

[tex] Number of moles of a substance= \frac{Given mass of a substance}{ Molar mass of substance} [/tex]

Here given mass of substance is 4540 g

Molar mass of the substance is 196 g mol⁻¹

So number of moles can be calculated as:

[tex] Number of moles of a substance= \frac{Given mass of a substance}{ Molar mass of substance} [/tex]

[tex] Number of moles of gold= \frac{4540}{196} [/tex]

So number of moles of gold =23.16 mol
