Answer:
n = 2 mol
Explanation:
Given data:
Pressure = standard = 1 atm
Temperature = standard = 273.15 K
Volume = 44.8 L
Number of moles = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
1 atm × 44.8 L = n × 0.0821 atm.L/ mol.K × 273.15 K
44.8 atm.L = n × 22.43 atm.L/ mol
n = 44.8 atm.L / 22.43 atm.L/ mol
n = 2 mol

The structure of Silver sulfide is composed of a single sulfur atom and two silver atoms. The chemical formula of silver sulfide is
Ag2S
When there are four atoms of silver available to produce silver sulfide, the maximum number of silver sulfide that can be produced is 2 since the four atoms is divided by 2.
