The value of for an unknown gas PV/nRT is equal to

Correct answer: A. 0.082 L.atm.mol-1.K

  • A. 0.082 L.atm.mol-1.K
  • B. 0.082 L.atm.mol-1.K-1
  • C. 0.82 L.atm.mol.K-1
  • D. 0.82 L.atm.mol.K

Explanation

The ideal gas law is represented by the equation PV=nRT, where:P is the pressure of the gas,V is the volume of the gas,n is the number of moles of the gas,R is the ideal gas constant, andT is the temperature of the gas in Kelvin.The value of the ideal gas constant (R) depends on the units used for pressure, volume, and temperature. The correct value with units commonly used is 0.0821 L.atm.mol−1.K−1Therefore, the correct option is a.0.082L.atm.mol−1.K−1.

About Atomic Structure

Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
