is there any corrolation between thermal conductivity coefficient and molecular wieght Mw

according to the units [K] W/(m·K) it is independant of mass units (kg or g/mol etc)

in my question i am asked to show with a graph, but i have no idea what graph they are talking about

 Admin Put thermal conductivity coefficient of Y axis and Mw on X axis and plot data points for any number of substances (the more, the better). Either there will be some obvious correlation or not. You may also try to make a plot for some selected group of substances, like alkali metals, or metals in general. -- chemical calculators - buffer calculator, concentration calculator www.titrations.info - all about titration methods
 using Al; Cu; Ag; Au; Pb this is the graph i got but how do i know if there is any correlation, i know its not linear,
