If the universal gas constant is `8.3J//"mole"//K` and the Avogadro's number is `6xx10^(23)`, then the mean K.E. of the oxygen molecules at `327^(@)C` will be

Avogadro's number is 6.023xx 10 ^(-23) .

The molar gas volume at S.T.P is 22.4 litre and Avogadro's number is 6.023 xx 10^(23) . Calculate (i) number of gas molecules per unit volume (ii) radius of gas molecule when mean free path is 1.1 xx 10^(-8) m .

The Avogadro's number is 6xx10^(23) per gm mole and electronic charge is 1.6xx10^(-19)C . The Faraday's number is

Universal gas constant R=8.3xx10^3 J/kmol K. The gas constant of one kg of nitrogen will be

Universal gas constant R=8.3xx10^3 J/kmol K. The gas constant of one kg of nitrogen will be

Avogadro's lasw states that under conditions of constant temp. and pressure equal volume of gases contain equal no. of particles. Experimental investigation shows that at one atmosphere pressure and a temperature of 273 k, one mole of any gas occupies a volume of which is very close to 22.4 lit. Therefore, the number of moles in any gas sample canbe found by comparing its volume at STP with 22.4 lit. If avagadro's number is 6xx10^(23) molecules then the mass of one atom of oxygen would be
