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)
