What is the theoretical yield of carbon dioxide gas on complete combustion of 250 grams of naproxen?

Complete combustion of naproxen takes place in excess of oxygen thus, naproxen is a limiting reactant and amount of carbon dioxide produced from it is theoretical yield of carbon dioxide.

The balanced chemical reaction for combustion of naproxen is as follows:

From the balanced chemical reaction, 1 mole of naproxen gives 14 mol of .

The mass of naproxen is given 250 g, molar mass is 230.259 g/mol thus, number of moles will be:

Thus, number of moles of obtained from 1.0857 mol of naproxen will be:

Now, convert this into mass as follows:

Molar mass of  is 44 .01 g/mol thus,

Thus, theoretical yield of is 669 g.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
