Let's call the initial temperature T1 = 290 K, and so the initial pressure is P1 = 1.80 ✕ 106 Pa. The final temperature is then T2 = 330 K. Calculate the final pressure. (Reminder—use the letter "e" to express scientific notation in your response. For example, if your answer is 1.2 ✕ 104, enter it as 1.2e4.) P2 = _________ Pa Let's try another example. Suppose we now have a gas initially at a pressure of 1.30 ✕ 106 Pa and a temperature of 400 K. The gas is in a cylinder with an adjustable piston sealing it in. We then reduce the volume of the container to one-third 1 3 of its original value, but maintain a constant pressure of 1.30 ✕ 106 Pa. What is the new final temperature (in K) of the gas? _______ K

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
