calculate the mass of 3.011*10^23 number of Nitrogen atoms.
The mass of 6.023 * 1023 atoms is 14 g.
So, mass of 3.011 * 1023 is 14* (6.023 * 1023 /3.011 * 1023 ) = 7 g
(i) Calculate the mass of 3.011 x 1023 nitrogen molecules. (ii) How many moles are 12.044 x 1023 atoms of He?
Calculate the mass of 3.011×1023 nitrogen molecule.
