(a) What is the value of PV/T where the curves meet on the -axis?
(b) If we obtained similar plots for kg of hydrogen, would we get the same value of PV/T at the point where the curves meet on the y-axis? If not, what mass of hydrogen yields the same value of PV/T (for low pressure high temperature region of the plot)? (Molecular mass of , of
(a) We will use
Mass of the gas is given as
Molecular mass of is given as
Number of mole given weight / molecular weight
(b) of does not represent the same number of mole.
For Example, molecular mass of is
So, number of moles of require is
Mass of required = no. of mole of molecular mass of
As a result, of would yield the same value
