Question

Num recipiente há 3,011 .  $10^{24}$ moléculas de certo gás. Quantos mols desse gás existem no recipiente??

Answer 1

N° de Avogadro = 6,02 * 10^23 para 1 mol

1mol -------------------- 6,02*10^23
xmols -------------------3,01*10^24

6,02*10^23*x=3,01*10^24

x = 3,01*10^24 / 6,02*10^23

x = 0,5 * 10^1

**************
x = 5 mols
