We’re being asked to calculate the number of moles of the hydrogen gas produced from a hydrolysis reaction that is collected over water.
Hydrogen gas is the natural form of hydrogen and it is a diatomic molecule.
Hydrogen gas → H2(g)
We’re going to calculate the amount of hydrogen gas in moles using the ideal gas equation.
P = pressure, atm
V = volume, L
n = moles, mol
R = gas constant = 0.08206 (L·atm)/(mol·K)
T = temperature, K
Let's first calculate the Partial Pressure of hydrogen gas:
Given: Total Pressure (Ptotal) = 739 mmHg
