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 chlorine and coke (carbon).

a) 2.01 mol TiO2 requires 4.02 moles Cl2 corresponding to 4.02 moles x 70.8 g/mole = 284.6 g Cl2
b) 2.01 moles TiO2 react with 2.01 g C corresponding to 2.01 moles x 12 g/mole = 24.12 g C
c) 2.01 moles TiO2 lead to the formation of 2.01 moles of TiCl4 and 2.01 moles CO2, corresponding respectively to: 2.01 moles x 189.5 g/mole = 380.9 g TiCl4 and 2.01 moles x 44 g/mole =88.dd g CO2
b) 2.01 moles TiO2 react with 2.01 g C corresponding to 2.01 moles x 12 g/mole = 24.12 g C
c) 2.01 moles TiO2 lead to the formation of 2.01 moles of TiCl4 and 2.01 moles CO2, corresponding respectively to: 2.01 moles x 189.5 g/mole = 380.9 g TiCl4 and 2.01 moles x 44 g/mole =88.dd g CO2

a. From the chemical equation, 1 mole of TiO2 reacts with 2 mols of chlorine gas.
so if TiO2 has 2.01 mole then chlorine gas has 4.02 mole (2.01 x 2)
b. 1 mole of TiO2 reacts with 1 mole of carbon
so if TiO2 has 2.01 mole then carbon has also 2.01 mole
to get mass; mole x Ar/Mr, and carbon has a relative atomis mass, Ar, of 12
so, 2.01 x 12=24.12g
c. 1 mole of TiCl4 and 1 mole of CO2 for product. (the ratio)
since TiO2 has ratio of one mole also and have 2.01 mol , then 2.01 mole of TiCL4 and 2.01
mole of CO2 formed.
so, for mass of TiCl4, 2.01 x 189.87=381.6g
for mass of CO2, 2.01x 44=88.44g
hence, total mass of product, 88.44 + 381.6=470.04g
(the 189.87 is the Mr of TiCl4 and 88.44 is the Mr for CO2)
hope this helps.
