Propane (C₃H₈) reacts with oxygen in the air to produce carbon dioxide and water. In a particular experiment, 38.0 grams of carbon dioxide are produced from the reaction of 22.05 grams of propane with excess oxygen. What is the percentage yield in this reaction?

Calculate the percent yield of CO2 when 28.16 g of CO2 are produced from the reaction of 4.000 moles of C8H18 with 4.000 moles of O2, given the reaction: 2 C8H18 + 25 O2 → 16 CO2 + 18 H2O.

Hydrogen gas (a potential future fuel) can be formed by the reaction of methane with water according to the following equation: CH4(g) + H2O(g) → CO(g) + 3H2(g). In a particular reaction, 26.5 L of methane gas (measured at a pressure of 730 torr and a temperature of 298 K) is reacted. If the actual yield of hydrogen gas is 60.0 L, what is the percent yield of hydrogen gas?

If the theoretical yield of NH₃ in a reaction is 40.0 g and the actual yield is 32.4 g, what is the percent yield?

If the theoretical yield of CO2 for the reaction is 160 g and the actual yield is 146 g, what is the percent yield of CO2 for the reaction? Express your answer to three significant figures.

What is the percent yield if 50 grams of barium phosphate is expected, but only 40 grams is actually produced?

When copper is heated with an excess of sulfur, copper(I) sulfide is formed. In a given experiment, 1.50 g of copper was heated with excess sulfur to yield 1.56 g of copper(I) sulfide. What is the percent yield?

A 0.510 g sample of strontium chloride reacts with sodium carbonate to give 0.455 g of strontium carbonate. What is the percent yield of strontium carbonate in this reaction?
