This Chemistry calculator has MathPrint, which can help in viewing equations in a natural textbook display.Explanation: . Since the gas is ideal, we can use a variation of the ideal gas law in order to find the unknown final pressure. Since we know that the number of moles is constant between both vessels (and R is a constant as well), we can simply compare the three factors being manipulated between the two vessels: pressure, volume, and temperature.
