How to Convert Grams to Moles: 8 Steps (with Pictures) - WikiHow
WebWe would multiply by T if we wanted to find something like pressure of volume. However, this problem asks us to solve for the number of moles of gas, or n. To do this, you can solve for n in the equation as Sal did, and get n = PV / RT. Here, you can see that to get n, we multiply pressure and volume, and then divide by temperature and R.
