An ideal gas equation can be written as, P = ρ R T M 0 where ρ and M 0 are respectively,

Options

  1. Amass density, mass of the gas
  2. Bnumber density, molar mass
  3. Cmass density, molar mass
  4. Dnumber density, mass of the gas

Correct answer

C. mass density, molar mass

Step-by-step solution

Recall the ideal gas equation, in terms of pressure, volume and temperature, P V = n R T ⇒ P = 1 V · m M 0 · R T , here R , is the universal gas constant, ⇒ P = m V R T M 0 ⇒ P = ρ R T M 0 , the density is defined as mass per unit volume, ρ = m v ,and, M 0 = the molar mass.
