Question

find the molar mass​

Answer 1

Given :-

Molar mass of :-

N (NITROGEN) = 14 amu

O (OXYGEN) = 16 amu

Na(SODIUM) = 23 amu

H (HYDROGEN) = 1 amu

S (SULPHUR) = 32 amu

A/Q =

(1) Na2S

23×2+32

46+32

==> 78 amu.

(2) NaNO3

23+14+16×3

23+14+48

23+62

==> 85 amu.

(3)NH3

14+1×3

14+1

==> 15 amu.

HERE,

FULL FORM OF AMU IS ATOMIC MASS UNIT.
