Chemistry

The data below relate to the adsorption of N2 on rutile (TiO2)at 75 K. Confirm
that they fit a BET isotherm in the range of pressures reported,and determine Vmon
and c.

p/kPa 0.160 1.87 6.11 11.67 17.02 21.92 27.29
V/cm3 235 559 649 719 790 860 950

At 75 K, p* = 76.0 kPa. The volumes have been corrected to 1.00atm and 273 K and
refer to 1.00 g of substrate

how do I know the intercept without graph excel in exam ?
