Question

Determinati volumul in conditii normale pe care il ocupa:
a). 56g NO
b). 3kmoli N2
c). 18, 066 * 10^25

Answer 1

V=U (nr de moli) *22.4
U=m(masa)/u(masa molara)
U=56/(14+16)=56/30=1.86 moli
V= 1.86*22.4=41,664 l

V=3000*22.4=67200 l
3kmoli=3000moli

U=18,066*10^25/6.023*10^25 =3 moli
V=3*22.4=67.2 l
