Question

density of a gas at 1.6 bar pressure and 273k is same as density of oxygen at stp, find molar mass of gas. ​

Answer 1

Answer:

Density is mass per unit volume. Finding the density of a gas is the same as finding the density of a solid or liquid. You have to know the mass and the volume of the gas. The tricky part with gases is that you are often given pressures and temperatures with no mention of volume. You have to figure it out from the other information.
