Question

Titanium is a transition metal used in many alloys because it is extremely strong and lightweight. Titanium tetrachloride (TiCl4) is extracted from titanium oxide using chloride and coke (carbon).

A) what mass of Cl2 gas is needed to react with 3.09 mol TiO2?

C) what is the mass of all the products formed by reaction with 3.09 mol TiO2

Answer 1

Mass of CO₂ = 135.96 g

Mass of TiCl₄ = 586.11 g

Mass of chlorine = 438.78 g

Step-by-step explanation:

Given data:

Moles of TiO₂ = 3.09 mol

Mass of Chlorine = ?

Mass of all product from 3.09 mol of TiO₂ = ?

Solution:

Chemical equation:

TiO₂ +C + 2Cl₂ → TiCl₄ + CO₂

Now we will compare the moles of chlorine with TiO₂.

TiO₂ : Cl₂

1 ; 2

3.09 : 2×3.09 = 6.18 mol

Mass of chlorine:

Mass = number of moles × molar mass

Mass = 6.18 mol × 71 g/mol

Mass = 438.78 g

Now we will compare the moles of TiCl₄ and CO₂ with TiO₂

TiO₂ : CO₂

1 : 1

3.09 : 3.09

TiO₂ : TiCl₄

1 : 1

3.09 : 3.09

Mass of CO₂:

Mass = number of moles × molar mass

Mass = 3.09 mol× 44 g/mol

Mass = 135.96 g

Mass of TiCl₄:

Mass = number of moles × molar mass

Mass = 3.09 mol× 189.68 g/mol

Mass = 586.11 g
