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

That can be mathematically represented as:


Number of moles of a substance= (Given mass of a substance)/( Molar mass of substance)

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:


Number of moles of a substance= (Given mass of a substance)/( Molar mass of substance)


Number of moles of gold= (4540)/(196)

So number of moles of gold =23.16 mol
