Step 1

Given:

Compound contains only titanium and oxygen.

Percent mass of titanium = 66.6 %.

Percent mass of oxygen = 100% - 66.6% = 33.4 %.

Molar mass of oxygen = 16 g/mol.

Molar mass of titanium = 47.867 g/mol.

Molar mass of compound = 144 g/mol.

Conversion of mass percent to gram:

Since we are having mass percent, it is convenient to use 100 g of the compound as the starting material. Thus, in the 100 g of sample of above compound 66.6 g of titanium and 33.4 g of oxygen.

Step 2

Calculation for number of titanium:

Step 3

Calculation for numb...
