The value of universal gas constant is R = 8.3 J/ k-mol. The value of R in atmosphere litre per kelvin per mol

As, R = 83 . J/K-molNow, u1  and  u2  are  units  while  n1  and  n2 are  the  numerical  values∴         n2=n1u1u2=8.3  J/K-molatm  L/K-mol=8.3  J/K-mol1.013×105  N/m210-3m3/K-mol=8.12102=0.0812∴   8.3  J/K-mol=0.0812  atm  L/K-mol
