Here's a precise problem for a chemistry student to solve:A gas, initially at a pressure of 1 atm and a temperature of 20°C, is contained in a cylinder with a volume of 5 L. If the gas is allowed to expand to a volume of 10 L at a constant temperature of 20°C, what is the final pressure of the gas? Use the ideal gas law equation to solve the problem.
