Question

Calculate the number of molecules of Oxygen gas that occupies a volume 224ml at 273k and 3 atom pressure

Answer 1

HEY!!!


You need to use PV=nRT. Use 0.224 L as V, 273 as T, 3 as P, and 0.082 as R. Your answer will give you number of moles of oxygen, which you an convert to number of molecules by multiplying moles by 6.02X10exp23.
