MOLAR VOLUME  , Z   (part 0)

(website: part1 and part2 ,thermodynamics)

meaning :  MOLAR VOLUME
ideal gases :   P*V =  R n*T  (a)
T = temperature          R= constant( SI =8.314)
P= pressure                 n = moles = mass(=gram)/MW
V= volume                    MW (= CO_2 = 44.01)

Def:   P.V/n = R.T   =>    V/n =V (=MOLAR  VOLUME=m^3/mol)

example : cylinder  with  volume 100l  (containing 50 Kg  CO_2 gas),MW (CO_2)=44.01

first :                conversion (Kg  => g   )    50kg = 50000g          (1kg = 1000g)
second:           conversion (l    => m^3)    100l  = 100*10^(-3)    (1m^3 = 1000l)

V : 100*10^(-3)/n;    /*m^3/mol */
