Question

DAU COROANA
Calculati numarul de moli continuti in 700 g $Al_{2} (Co_{3}) _{3}$= carbonat de aluminiu
MAl2(Co3)3= 27*2+12*3+16*3*3= 54+36+144=234   (Masa moleculara am calculat-o eu)
AAl=27
Ac=12
AO=16

Answer 1

1mol Al2(CO3)3...........................234 g
x...............................................700 g
X= 700/234
X= 2,99 ≈ 3 moli
