Solution: Hydrogen produced from a hydrolysis reaction was collected over water and the following data was compiled. Calculate the moles of hydrogen gas produced by the reaction. 

Problem

Hydrogen produced from a hydrolysis reaction was collected over water and the following data was compiled. 

Calculate the moles of hydrogen gas produced by the reaction. 

Solution

To calculate the moles of gas we need to use the ideal gas equation:



For problems that involve collecting gas over water, we should note that the total pressure is the sum of the partial pressure of the gas and water. So still need to calculate the actual pressure that we will use for the ideal gas equation.
