A 2.31 g sample of a mixture of AgNO3 and NaNO3 is treated with excess Na2S(aq). The precipitate is filtered off, dried and weighed. The dried precipitate weighs 0.47 g. What is the percentage by mass of NaNO3 in the original mixture? Your answer must be accurate to two significant digits. Keep several extra digits in your calculations and round off only at the end. Do not include the percent sign (%) as part of your answer! Molar masses (in...

A 5.37 g mixture of sodium chloride and sodium carbonate is heated to decompose the sodium carbonate into sodium oxide and carbon dioxide according to the following chemical equation. Na2CO3 → Na2O + CO2 The sodium chloride will not decompose. If the final mixture has a mass of 4.03 g, what was the percent sodium carbonate in the original mixture? Hint: Consider the Law of Conservation of Matter - the mass of reactants must equal the mass of products. However,...
