Question

Calulate the values of R (universal gas constant) and Boltzmann’s constant at STP

Answer 1

Answer:

R=8.314J/Mol.K

K=1.38×10^-23J/K

Explanation:

we know the relation for ideal gas is   PV=nRT

at STP(standard temperature and pressure) conditions,

pressure=101325

volume=0.00224

n(moles)=1

temperature=273K

from the relation

R=PV/nT

R=(101325×0.0224)÷(1×273)

R=8.3138J/Mol.K, it can be written as

R=8.314J/Mol.K

we know the relation

i.e.,boltzmann constant(k)=Gas constant(R)/Avogadro no(N)

K=8.314/6.022×10^23

K=1.38×10^-23J/K
