Answer to Question #202738 in General Chemistry for Louis Kator

Question

at standard temperature and pressure one mole of gas occupies a volume on 22.415dm³ , exert a pressure of one atmosphere at 0°c . Calculate the molar gas constant

Answer 1

We use for this problem Mendeleev Klapiron's formula

pV=nRT from there R=pV/nT

0⁰C=273K

22.415dm³=22.415L

R=1atm*22.415L/1mol*273K=0.82L*atm*mol^-1*K^-1
