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?

In a chemical reaction, if the theoretical yield is 50 grams and the actual yield is 40 grams, what is the percent yield?

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?

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?
