If the value of Avogadro number is 6.023times10^(23)mol^(-1) and the value of Boltzmann constant is 1.380times10^(-23)JK^(-1),then the number of significant digits in the calculated value of the universal gas constant is

If the value of Avogadro numberis 6.023xx10^(23)mol^(-1) and the vaueof Boltzmann constant is 1.380xx10^(-23)JK^(-1) , then the number of significant digits in the calculated value of the universal gas constant is

Calculate the value of universal gas constant at STP .

Why is the value of Avogadro's number 6.022 xx 10^(23) and not any other value ?

The value of Planck's constant is 6.62618 xx 10^(-34)Js . The number of significant figures in it is

The number of significant figures in 6.023xx10^(23) "mole"^(-1) is

Given, Avogadro's number N = 6.02 xx 10^23 and Boltzmann's constant k = 1.38 xx 10^-23 J//K . (a) Calculate the average kinetic energy of translation of the molecules of an ideal gas at 0^@ C and at 100^@ C . (b) Also calculate the corresponding energies per mole of the gas.
