6. Incorrect equation for an ideal is
a) PV = nRT
b) Pv = RT
c) PM = ρRT
d) None of the mentioned
where: P – Absolute Pressure of the gas
V – Total volume occupied by the gas
n – Number of moles of the gas
T – Absolute temperature
v – Specific molar volume
ρ – Density of the gas
View Answer
Explanation: All three are correct as a & b are ideal gas law and c is in the form of density.
