Answer

Explanation:

Step1: Find molar - mass of TiO₂

The molar mass of Ti is approximately 47.87 g/mol and O is approximately 16.00 g/mol. For TiO₂, the molar mass $M = 47.87+2\times16.00=47.87 + 32.00=79.87$ g/mol.

Step2: Calculate moles of TiO₂

Use the formula $n=\frac{m}{M}$, where $m = 77$ g and $M = 79.87$ g/mol. So $n=\frac{77}{79.87}\approx0.96$ mol.

Answer:

0.96
