Question

Air contains 21 percent of oxygen by volume. Calculate theoretical volume of air which is required for burning 500 cubic feet acetylene

Answer 1

Answer:

$(Steam) Here, the ratio of the reacting molecules and those of the products is taken as the ratio of their volumes. This is in accordance with Avogadro's hypothesis-equal to volumes of all gases under similar conditions of temperature and pressure contain equal number of molecules or its reverse, namely, equal number of molecules under similar conditions of temperature and pressure occupy equal volumes, is equally true.) The ratio by volumes of reactants and products is apparently simple.
