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 chemistry student is investigating the surface area of activated carbon for an adsorption experiment. Using BET theory of multilayer adsorption, determine the specific surface area of the activated carbon based on the following data: - Mass of activated carbon used: 0.25g- Nitrogen adsorption at various pressures (in mmHg): - 6.523 - 9.785 - 13.092 - 19.638 - 31.725 - 45.200 - 61.587 - 84.632 - 114.684 - 147.087 Assume that the area occupied by one nitrogen molecule is 0.162 nm², and use the BET equation to calculate the specific surface area of the activated carbon material.
