What is the number of significant figures in Avogadro's number `(6.0 xx 10^(23))` and Planck's constant `(6.62 xx 10^(-34) J s)`.

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

Find the number of significant figures in the following constants: (i) 6.626 xx 10^(-34) Js (Planck's constant) (ii) 6.02 xx 10^(23) (Avogadro's number) (iii) 1.097 xx 10^5 cm^(-1) (Rydberg's constant). (iv) 5.29 xx 10^(-9) cm (First Bohr's radius in H)

The number of significant figures in 6.02xx10^(23) is

The number of significant figures in 1.00 xx 10^6 is:

Calculate the number of significant figures in the following values : (a) Planck's constant = 6.626 xx 10^(-34) J s (b) Avogadro number = 6.023 xx 10^23 (c) Velocity of light = 3.0 xx 10^8 m s^(-1) (d) Electronic charge = 1.602 xx 10^(-19) C
