The density of an unknown gas at STP is 1.43 g/L. What is the molar mass of the gas?

The product of pressure and volume $\left( {PV} \right)$ has a unit of:

A certain mass of gas occupies a volume of 300 cc at 27\,^\circ C and 620 mm pressure. The volume of this gas at47\,^\circ C and 640 mm pressure will be

Equal volumes of two gases which don’t react together are confined in separate vessels. Their pressure is 100 mm and 300 mm of Hg respectively. If the two vessels are joined together, then what will be the pressure of the resulting mixture? (Temperature remains constant)

The condition of SATP refers for:

Pressure remaining the same, the volume of a given mass of an ideal gas increases for every degree centigrade rise in temperature by a definite fraction of its volume at:

At constant pressure, the volume of a gas increases when its temperature:

Normal temperature and pressure ${\rm{(NTP}})$ of gases refers to:

Volume occupied by molecules of one mole gas at NTP, each having radius of ${10^{ - 8}}$ cm is:

The density of a gas $A$ is twice that of a gas $B$ at the same temperature. The molecular weight of gas $B$ is thrice that of $A$. The ratio of the pressures acting on $A$ and $B$ will be

Air at sea level is dense, this is a practical implementation of
