What is Avogadro’s law of gases?

Ans. Equal volume of all ideal gases contain equal number of molecules at S.T.P.

Justify that 1 cm3 of H2 and 1 cm3 of CH4 at STP will have same number of molecules. When one molecule of CH4 is 8 times heavier than that of hydrogen.  

Ans. According to Avogadro’s law “ Equal volume of all ideal gases contain equal number of molecules at S.T.P.”

1 cm3 of H2 and 1 cm3 of CH4 have same volume so these have same number of molecules.

No doubt CH4 is 8 times heavier than that of hydrogen, but volume not depends upon sizes and masses of molecules.

      Van der Waal's equation | 1st year chemistry unit 3 Why the volume correction is done by van der Waal? Ans. Actual volume of gas molecules is not negligible as compared to the total volume of vessel. Therefore, Van der Waal corrected the volume factor in general gas equation. So, excluded volume is subtracted from total volume of vessel to get the free volume available for gas molecules.                                       V free = V vessel – b (excluded volume) Why the pressure correction is done by Van der Waal? Ans. Forces of attraction present between molecules of real gas. Therefore, Van der Waal corrected the pressure correction in general gas equation. Lessened pressure is subtracted from ideal pressure to get the observed pressure.        ...

      Graham's law of diffusion | chemistry class 11 | fsc part 1 | chemistry notes Q) Define diffusion. Give examples. Ans. The spontaneous mixing of the molecules of different gases by random motion and collisions to form a homogeneous mixture is called diffusion. Examples:     i) The spreading of fragrance of rose in air                    ii) The gases of balloon diffuse in air after its burst.   Q) Define effusion. Give examples. Ans. The escaping of gas molecules one by one through a tiny hole into an evacuated space is called effusion. Example: An inflated balloon gradually becomes smaller in size due to its effusion.   Q) State Graham’s law of diffusion. Write its mathematical form. Ans. The rate of diffusion or effusion of a gas is inversely proportional to the square root of its density at constant temperature and pressure. Mathematical form...

      Dalton law of partial pressure. 1st year chemistry chapter 3 short questions notes. Dalton law of partial pressure class 11   Q) State Dalton's law of partial pressure. Why is it necessary that no forces of attractions should be there to obey this law?   Ans. Statement : Total pressure exerted by mixture of gases is equal to sum of individual partial  pressures of gases at given temperature.  Mathematically:    P t = P 1 + P 2 + P 3 If forces of attraction present between molecules of gases then total pressure will be less than individual partial pressure of gases. Therefore it is necessary that no forces of attraction should be there to obey this law.   Q) Define Mole fraction of gas. Ans. It is the ratio of number of moles of a gas to the total number of moles of gases present in a mixture. Its value always smaller than 1. Q) What is partial pressure? Give its formula. Ans. Partial pressure is the pressure which is exerted by a gas...
