Question

Cati atomi de H2 contine 5.6 litri de NH3

Answer 1

Răspuns:

n NH3 = V NH3 / Vm = 0.25 moli NH3

1 mol NH3 ............. 3 moli H

0.25 moli NH3 ................ x

Obtinem : x = 0.75 moli H

1 mol H .................. 6.022*10^23 atomi

0.75 moli H .................... y

Obtinem : y = 4.5165*10^23 atomi H
