Question

calculate the percentage by mass of titanium in titanium(IV) chloride(TiCl4). Give your answer to 3 significant figures. Relative atomic masses (Ar): Cl = 35.5; Ti = 48

Answer 1

The percentage by mass of titanium in titanium(IV) chloride is 25.4%.

Step-by-step explanation:

To calculate the percentage by mass of titanium in titanium(IV) chloride (TiCl4), we need to determine the molar mass of TiCl4. The molar mass can be calculated by adding the atomic masses of each element in the compound.

The atomic masses of Ti and Cl are 48 g/mol and 35.5 g/mol, respectively.

To calculate the molar mass of TiCl4, we add: Molar mass of TiCl4

= (48 g/mol) + 4(35.5 g/mol)

= 189 g/mol

Next, we calculate the mass of titanium in TiCl4 using the molar mass:

Mass of titanium = (48 g/mol / 189 g/mol) x 100%

= 25.4%

Therefore, the percentage by mass of titanium in titanium(IV) chloride is 25.4%.
