If the value of Avogadro number is 6.023 xx 10^23 mol^(-1) and the value of Boltzmann constant is 1.380 xx 10 ^(-23) J K^(-1) , then the number of significant digits in the calculated value of the universal gas constant is

The Avogadro number is 6.022 xx10^(23) . How many significant figures are there ?

The activity of 1 g. of a sample of Po^210 is 4442 Ci. Determine the half-life of the element. (Avogadro's number = 6.023xx10^23 )

A silver atom in a solid oscillated in simple harmonic motion is some direction with a frequency of 10^(12)s^(-1). What is the force constant of the bonds connecting one atom with the other? (mole wt. of silver = 108 and Avogadro number = 6.02 xx 10^(23) g. "mol"^(-1) )

The half-life of U^238 is 4.5xx10^9 y. In any radioactive sample if 1 g. of that element remains present then determine the activity of the sample in curie unit. (Avogadro number = 6.023xx10^23 ).
