367.2 g of silver
Explanation:
To find the mass of a substance knowing the number of moles we use the following formula:
number of mole = mass / molecular weight
In the case of silver we use the atomic weight of 108 g/mole.
mass = number of moles × molecular weight
mass of silver = 3.4 moles × 108 g/mole
mass of silver = 367.2 g

Mass of Cl₂ : 164.01 g
<h3>Further explanation</h3>
A mole is a number of particles(atoms, molecules, ions) in a substance
This refers to the atomic total of the 12 gr C-12 which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles
Can be formulated :
N = n x No
N = number of particles
n = mol
No = 6.02.10²³ = Avogadro's number
mol Cl₂ :

mass Cl₂(MW=71 g/mol) :
