Molar mass FeTiO3 => 151.7102 g/mol
atomic mass Ti => 47.867 u
% ( atomic mass Ti / molar mass FeTiO3 ) x 100
= ( 47.867 / 151.7102) x 100
= 0.3155 x 100
= 31.55 % of Ti
hope this helps!

you welcome
Answer:
Yes, it is possible.
Explanation:
A diprotic acid is an acid that can release two protons. That's why it is called diprotic.
Monoprotic → Release one proton, for example Formic acid HCOOH
Triprotic → Releases three protons, for example H₃PO₄
Polyprotic → Release many protons, for example EDTA
it is a weak acid.
In the first equilibrum, it release proton, and the second is released in the second equilibrium. So the first equilibrium will have a Ka1
H₂A + H₂O ⇄ H₃O⁺ + HA⁻ Ka₁
HA⁻ + H₂O ⇄ H₃O⁺ + A⁻² Ka₂
The HA⁻ will work as an amphoterous because, it can be a base or an acid, according to this:
HA⁻ + H₂O ⇄ H₃O⁺ + A⁻² Ka₂
HA⁻ + H₂O ⇄ OH⁻ + H₂A Kb₂
Given the mass of aluminum sulfide
= 21.0 g
Molar mass of = 
Calculating the moles of :
Each mole has 3 mol S.
Each mole S constitutes 
Calculating atoms of S in 0.14 mol :
=
