Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as

Answer:
Explanation:
1 Al = 26.98 AMU
3 Br = 239.7 AMU
AlBr3 = 266.69 AMU
Al = (26.98)/(266.69) = 10.1%
Br3 = (239.7)/(266.69) = 89.9%
