Answer:

1.82moles

Explanation:

Mass = 357.80g

Molar mass of gold (Au) = 196.97g/mol

Number of moles = mass / molar mass

Number of moles = 357.80 / 196.97

Number of moles = 1.8165 moles

The number of moles is approximately 1.82molespresent in 357.80g of Au

Answer:

[tex]moles_{Au}=1.8166molAu[/tex]

Explanation:

Hello,

In this case, since one mole of an element is related with its atomic mass, for gold whose atomic mass is 196.96657 g/mol, the corresponding number of moles turn out:

[tex]moles_{Au}=357.80gAu\times \frac{1molAu}{196.96657g Au} \\\\moles_{Au}=1.8166molAu[/tex]

Best regards.
