Question

Caliculate the value of the gas constant for one gram of hydrozen given that the density of hydrozen 0.00009g/cm3

Answer 1

Answer:

4.12J/K-g

Explanation:

Density of hydrogen at S.T.P =0.00009g/cm^3

volume of 1g of hydrogen=1/0.00009litre=1000/0.00009c.c

At S.T.P,pressure =76*13.6*980 dyne /cm^2

Temperature=273K;gas constant,r=pv/T

=(76*13.6*980)(1000/0.00009)÷273

=76*13.6*98*10^9/273*9

=3,339.3*10^9=33.39*10^7 erg/gm/K

=~4.12J/gm/K
