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

The formula for K+ and S-2 is K2S because you need 2 potassium ions to balance out the sulfide ion
Answer:
The particles that compose a gas are so small compared to the distances between them that the volume of the individual particles can be assumed to be negligible.
Explanation:
This is a postulate of the Kinetic Molecular Theory.
A is wrong. KMT assumes the that the volume of the particles is negligible.
B is wrong. KMT assumes that the distance between the particles is muck greater than their size.
D is wrong. It takes the large distances as a fact. KMT uses this as an assumption.
