Now we can say that the ideal gas law can be used to determine the density of a gas under certain pressure and temperature conditions. Here, we're going to say that the new derived version of the ideal gas law, which we can apply to density, is d equals P times em over r t. And to help us remember this order chest, remember, dreams push me over rough times here Dreams D Stands for density. Push me is pressure times molar mass over our times team rough times. So if you could remember this phrase, it's a great way to remember this version of the ideal gas law when it relates to density. Now, if you wanna look and see how we derive this formula, you can click on to the next video, but only do so if you're a professor. Really cares on how you derive these different types of formula. If they don't, they just remember this phrase. After that, go to the next series of videos and let's put this formula to practice
