1 litre of a gas at NTP weights 0.5 gm .What is the molecular weight of the gas ?

1 litre gas at NTP weight 0.5 g what is molecular mass of gas ?

If 5.6 litere of a gas at NTP weights 8.25 g its vapour density ?

The measured density of helium gas at NTP is 0.1784 gm per litre. What is the weight of 1 mole of this gas ?

What is inter molecular distance in case of a gas ?

At 720 mm pressure and at 27^@ C , 200 mL of gas weight 1.653g . Calculate its molecular weight using general gas equation.

The vapour pressure of a solution of a non-volatile electrolyte (B) in a solvent (A) is 95% of the vapour pressure of the solvent at the same temperature. If the molecular weight of the solvent is 0.3 times the molecular weight of solute, the weight ratio of the solvent and solute are:

If the equivalent weight of a tri- valent metal is 32.7. the molecular weight of its chloride is ,
