Question

calculate number of atoms is each of the following (average atomic mass :n=14u, s=32)a)0.4 mole of nitrogen​

Answer 1

Answer:

first calculate the given weight, from

n=given wt./molecular wt.

Explanation:

given wt. = mol. wt.× no. of moles(n)

= 14× 0.4

=5.6

now, no. of atoms = 0.4× 6.023×10^23
