Calculate the percentage of oxygen in \(Al_2(SO_4)_3\) (atomic mass: \(Al=27\), \(O=16\), \(S=32\)).
Answer:
Given data:
Atomic masses:
\(Al=27\), \(O=16\), \(S=32\)
Formula:
The formula to find the percentage of an element is
\(\frac{\text{X}}{\text{Y}}\times100\)
Where,
X \(=\)
Y \(=\)
Solution:
Molecular mass of \(Al_2(SO_4)_3\) \(=\)
% of \(O\) in \(Al_2(SO_4)_3\) \(=\)
