Question

29. The molecular mass of Aluminium
Oxide (Al = 26, O = 16): *​

Answer 1

Answer:

formula of Aluminium Oxide is Al2 O3

so, molecular mass of Aluminium Oxide is {(2×26) + (3×16)} unit

that is, molecular mass of Aluminium Oxide = {52+48}u = 100u

Hence, the molecular mass of Aluminium Oxide is 100u.
