1. Assume that, for a laboratory assignment, you need 15 mL of 2.5M potassium hydroxide (KOH). All you can find, however, is a bottle of concentrated potassium hydroxide with a strength of 16M. Clearly explain, using calculations as necessary, how you would obtain the 15 mL of 2.5M potassium hydroxide that you need.
You have a tank of helium with a volume of 10 liters that is currently under 40 atm of pressure. If you open the valve on the tank and release the helium into a room with a volume of 10,000 liters, how many atmospheres of pressure will the helium now be under? Second, what will happen to the "space" between the helium atoms? Clearly explain your answer, including any assumptions you may need to make in order to answer the question.
