b. The volume over the solution is 122 mL. Calculate the partial pressure of the hydrog gas in this volume at 25°C, ignoring any solubility of the gas in the solution.

Solution

Answer:

Given volume V=122 mL=0.122 L (1L=1000 mL)

and Temperature T=25°C=25+273 K=298 K

From Ideal gas equation, PV=nRT

where P= pressure, V= volume, n= number of moles=1 here, R= gas constant=0.0821 Latm/mol.K and T= temperature.

P=RT/V=(1 mol x 0.0821  Latm/mol.K x 298 K)/0.122 L

Pressure P=200.54 atm.
