Question

If you have 1.4 grams of silver (Ag), how many moles of silver do you have?

Answer 1

Answer: There are 0.0129 moles of silver present in 1.4 grams of silver (Ag).

Explanation:

Given: Mass of silver = 1.4 g

Number of moles is the mass of substance divided by its molar mass.

As molar mass of silver is 107.86 g/mol. Therefore, moles of silver are calculated as follows.

$No. of moles = \frac{mass}{molar mass}\\= \frac{1.4 g}{107.86 g/mol}\\= 0.0129 mol$

Thus, we can conclude that there are 0.0129 moles of silver present in 1.4 grams of silver (Ag).
