Question

the density of a gas is 3 (density of oxygen is 1) under the same conditions the molecular weight of the gas is​

Answer 1

Answer: 6:1

Explanation: P=dRT/M

Where R and T are constants

And P is pressure, d is density,Mis molecular weight

Therefore, P[A]/P[B] = {d[A]/d[B]}/{M[A]/M[B]} = 2×3 = 6

Hence,P[A]/P[B] = 6:1

YOU CAN EVEN WRITE THE ANSWER AS 1:6 ACCORDING TO THE OPTIONS AVAILABLE...
