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).

Step-by-step 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 = (mass)/(molar mass)\\= (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).
