The mass of gas adsorbed, x, per unit mass of
adsorbate, m, was measured at various pressures,
p. A graph between $$\log {x \over m}$$
and log p gives a
straight line with slope equal to 2 and the intercept
equal to 0.4771. The value of
$${x \over m}$$
at a pressure of
4 atm is :

(Given log 3 = 0.4771)

(Given log 3 = 0.4771)
