Concept of Ideal Gas Equation Explained

What is the equation of state corresponding to 8 gm of Oxygen (O2)?

A. PV=RT
B. RT/4
C. RT/3
D. RT/2

Answer:

Option (B) RT/4 is the correct answer.

The ideal gas equation is represented as PV = nRT, where n is the number of moles. In this scenario, when 8 grams of oxygen (O2) are present, the number of moles is calculated as follows:

Number of moles = mass of atom / molar mass of the atom

Number of moles = 8 / 32

Number of moles = 1/4

Substituting the value of n into the ideal gas equation PV = nRT:

PV = nRT

PV = (1/4)RT

Therefore, the equation of state corresponding to 8 gm of Oxygen is RT/4. This equation explains the relationship between pressure, volume, temperature, and the number of moles of a gas in an ideal gas scenario.
