What is the density of ammonia gas (molar mas of 17.03) at STP?
The Attempt at a Solution
So, i know that to find density, i need to have volume (d=m/v). To begin with, I plugged in my values into pv=nrt only to realize that i was missing moles. this might just be a chem issue, but can anyone refresh me on how to find the moles using the given? :/
