Additional question to Ethylene Dibromide?
how did you come up with the equation d=Mp/RT?
Answer:
if a=b
and b=c,
therefore a=c.
third grade elementary school !!!
the guy has written it plain and simple.
density is m/V, and m=n.M, therefore density is M.n/V.
we know that n/V=p/RT from the universal gas law.
now substitute the right side of this equation, (since n/V should be n/V no matter what) in the above one about the density and you get exactly what the guy says.
