Answer to Question #63355 in General Chemistry for Festus

Question

mass of carbon is 1.2g and 3.4g, mass of oxygen is 3.2g and 2.4g. show that this figures are in accordance with the law of multiple proportion

Answer 1

We have to recalculate masses into the molar quantities:
1.2g/12g/mol(Carbon) - 3.2g/16g/mol(Oxygen) = 1:2 or CO2
3.4g/12g/mol(Carbon) - 2.4g/16g/mol(Oxygen) = 2:1 or C2O
