//To calcluate the TCE concentration
disp('What is the TCE concentration in g/m^3 for each of the following')
disp('example 9.1 a')
disp( 'A soil having a density of of 2 g/cm^3 with TCE concentration of 4 ppm')
// Since density is given in cm^3 it has to be converted into m^3
density=2*1000
//Since 1ppm= 1/10^6 g, we get
ppm = 4/10^6

TCE= ppm*density
