Question

4. How many moles of silver are in a ring that contains 3.50 grams of silver?

Answer 1

Answer:

3.5g/{molar mass of silver}

3.5g/(107.86g/mol)

now we have 0.03244mol of silver

Answer 2

The statement of the moles of silver is "0.0324 mol."

What is mole?

The mole is a SI unit of measurement that is used to determine the amount of any substance that need to be given in mol. The mole is the amount of substance in a system that has the same number of fundamental entities as atoms in 0.012 kilogramme of carbon 12.

In order to determine the moles, divide the mass of the substance by its molar mass to convert grams into moles.

Grams to moles conversion factor,

$Grams\;.\;\frac{1\;mol}{grams}\;=\;Moles$

Moles of silver comes out to be,

$=\frac{Grams}{molar\;mass} \\= 3.50\;g\;.\;\frac{1\;mol}{107.86\;g} \\= 0.0324\;mol$

Hence the correct answer is 0.0324 g of Ag.
