Question

Calculate the value of the gas constant for one
gram of hydrogen, given that the density of
hydrogen at N.T.P is 0.00009 g/cm3
1)4.12J/K-g 2)2.12J/K-g
3) 5.12J/K-g
4)3.12J/K-g

Answer 1

4.12j/kg

Explanation:

density of hydrogen =0.00009g/cm3

volume of 1g of hydrogen=1/0.00009

At stp pressure =76×13.6×980 dune /cm3.

gas constant K=PV/T.

=76×13.6×989×(1/0.00009×273)

=4.12j/kg
