Which of the following expressions is true for an ideal gas?

A pre-weighed vessel was filled with oxygen at NTP and weighed. It was then evacuated, filled with SO₂​ at the same temperature and pressure, and again weighed. The mass of oxygen will be?

A gas behaves most like an ideal gas under conditions of:

The compressibility factor of a gas is less than unity at STP. Therefore,

Equal masses of ethane and hydrogen are mixed in an empty container at 25^oC. The fraction of the total pressure exerted by hydrogen is?

There are 6.02×10²² molecules each of N_2​,O_2​ and H₂​ which are mixed together at 760 mm and 273 K. The mass of total mixture in grams is

Vapour density of a gas is 11.2. The volume occupied by 11.2 g of this gas at STP is:

When an ideal gas undergoes unrestrained expansion, no cooling occurs because of the molecules:

An ideal gas obeying kinetic gas equation :

A bottle of cold drink has 200 mL liquid in which CO₂​ is 0.1 molar. If CO_2​ behaves as ideal gas the volume of C0_2​ at S.T.P. solution of cold drink is
