Create a function m-file called Chemistry.
Benzene,molecular weight=78.115 g/mol
Ethyl alcohol, mol.weight=46.07 g/mol
Tetrafluoroethane, mol.weight=102.3g/mol
mass=number of moles * mol.weight
The function Chemistry requires 2 vector inputs ie number of moles and mol.weight and returns the corresponding mass. It will be necessary to use meshgrid in the calculations
Test the function with the compounds listed in the above table for values of n (number of moles) from 1 to 10.
I am not sure of how to go about this, any help would be appreciated. Thank you!

I don't know what the sentence starting "Benzene....." is supposed to be. You forgot to say. Care to explain? And you already gave the function, pretty much
function mass = Chemistry(number_of_moles, mol_weight)
mass=number_of_moles * mol_weight;
I don't see at all how meshgrid is supposed to be involved in that. Seems like you need to read these links: http://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer and http://www.mathworks.com/matlabcentral/answers/8626-how-do-i-get-help-on-homework-questions-on-matlab-answers

The compounds are just a table of compounds and their molecular weights. The last part of the question uses it, thanks for your help
