When man initiate to go outer space:
Many times ago, people used to think about the world out of Earth, the space and the sky. These thoughts generated the idea of thinking and imagining the space and the moon.
The idea turned into a movie by Georges Méliès, which was inspired by a book written by Jules Verne. The movie gave the idea to Konstantin Tsiolkovsky, a Russian man to develop many ideas which were implemented by Russia and America to build airplanes and rockets that we see launching at present.
A small though became an idea which gave birth to a new invention through which people live their dreams of going in the outer space. Incredible!

Explanation:
Answer:
n = 0.072 mol
Explanation:
Given data:
Volume of gas = 3.80 L
Temperature of gas = 320 K
Pressure of gas = 0.496 atm
Number of moles of Ar gas = ?
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
Now we will put the values.
n = PV/RT
n = 0.496 atm ×3.80 L / 0.0821 atm.L/ mol.K × 320 K
n = 1.88 /26.27 /mol
n = 0.072 mol
