Question

1.44 g of Titanium (Ti) reacted with an excess of O₂ and produced x g of a non-stoichiometric compound Ti_1.44O₁. The value of x in g is :

• A. 1.44
• B. 2
• C. 1.77
• D. None of these

Answer 1

Answer: (C)

Ti + O₂ $ \rightarrow $ Ti_1.44 O
(1.44 g) (x) g
Apply POAC to Ti
$\left(\right. \frac{1.44 \text{g}}{48} \left.\right) \times 1 = \left\{\right. \frac{\text{x} \text{g}}{\left(\right. 1.44 \times 48 \left.\right) + 16} \left.\right\} 1.44$
x = $\frac{4 8 \times 1 \text{.} 4 4 + 1 6}{4 8}$
= $1 \text{.} 4 4 + \frac{1 6}{4 8}$
= 1.44 + 0.33
= 1.77 g.
