Question

what is mass of in unit of 1 mole of nitroge atom

Answer 1

Actually mass of 1 atom of nitrogen is 14 u

(u=atomic mass unit)

Mass of 1 mole=mass of 1 atom of nitrogen * Avagadro's no * 1.6 *10⁻²⁴

(since 1 amu=1.6* 10^(-24) gm)

=14*6.022*10²³*1.6* 10⁻²⁴ =14 gm

:)

Answer 2

Molecular mass of Nitrogen =[no.of atoms x
atomic mass]
= 1x14
= 14u
Mass of 1 mole of N = 14g
