Question

Cantitatea de magneziu care conţine 2,4088 * 10(24) atomi de magneziu (AMg = 24)​

Answer 1

Răspuns:

Explicație:

2,4088.10 la 24= 24 , 088 .10²³

1mol de atomi Mg----------6,022.10²³atomi Mg

xmoli----------------------------24,088.10²³ Mg

x = n= 24,088 .10²³ : 6,022 . 10²³= 4moli de atomi de Mg

n= m : M

m= n . M

m= 4moli . 24g/moli = 96 g Mg
