Consider a container separated into two compartments by a barrier. One compartment has a gas at a pressure of 1 atm and the other compartment is empty. The barrier has a small hole in it, which allows the gas to diffuse from one compartment to another. If the rate of diffusion of the gas is 0.2 mL/min and the molar mass of the gas is 28g/mol, what is the mass of gas transferred through the hole in 5 hours?

A student is given the electrochemical cell reaction:MnO4-(aq) + 8H+(aq) + 5e- → Mn2+(aq) + 4H2O(l)Calculate the standard potential (in volts) of the cell at 25°C given that the standard reduction potential of MnO4-(aq)/Mn2+(aq) couple and the standard reduction potential of the H+(aq)/H2(g) couple are +1.51 V and 0.00 V, respectively. The concentration of MnO4-(aq) is 0.010 M and that of H+(aq) is 1.00 M.
