AI-generated answer To determine the grams of hydrogen collected, we need to use the ideal gas law equation, which relates the amount of a gas to its pressure, volume, and temperature. The ideal gas law is given by the formula: PV=nRT Where: - P = Pressure (in atm) - V = Volume (in liters) - n = Number of moles - R = Ideal gas constant (0.0821 mol⋅K atm⋅L ​ ) - T = Temperature (in Kelvin) Given data: - Partial pressure of hydrogen gas (PH2) = 723.2 mm Hg = 0.951atm (since 1atm=760mmHg) - Volume (V) = 682 mL = 0.682L - Temperature (T) = 310.55 K Step 1: Calculate the number of moles of hydrogen gas using the ideal gas law: n= RT PV ​ n= (0.0821 mol⋅K atm⋅L ​ )(310.55K) (0.951atm)(0.682L) ​ Step 2: Calculate the grams of hydrogen gas using the molar mass of hydrogen (H 2 ​ ) which is approximately 2.016g/mol: m=n×Molarmass m=n×2.016g/mol Substitute the value of 'n' from step 1
