Question

MATLAB

The atmosphere on Mars is very different from the atmosphere on the Earth. Here is the breakdown of Mars' atmosphere composition: Carbon dioxide Argon Nitrogen Oxygen Carbon monoxide 95.97% 1.93% 1.89% 0.15% 0.06% Carbon dioxide, Argon, Nitrogen, Oxygen and Carbon monoxide have molar masses of 44 g/mol, 39 g/mol, 28 g/mol, 32 g/mol, and 28 g/mol separately. Please use MATLAB to calculate the average molar mass (unit: g/mol) of the atmosphere on Mars. Write or attach your MATLAB code/file.

Answer 1

%% Matlab code

c=[0.9597 0.0193 0.0189 0.0015 0.0006];
mm=[44 39 28 32 28];
av_mm=sum(c.*mm)/sum(c);
fprintf('Average molar mass = %f g/mol \n',av_mm);

OUTPUT:

Average molar mass = 43.573500 g/mol
