calculate the density of NO3 gas at 0.970mm Hg and 35C

Take 1 liter.

calculate n in PV=nRT

then, density= mass/volume= (n*molmassNO3)/1liter.

I STILL DONT UNDERSTAND HOW TO DO IT COULD U PLEASE EXPLAIN

What don't you understand about

PV = nRT and how that fits your problem. Or is it the density part? Please be specific.
