Tio2 + 4cl2 + 3c → co2 + 2co +2ticl4 how many moles of ticl4 will be needed to react with 115 moles of cl2? a. 230 mol b. 115 mol c. 76.7 mol d. 57.5 mol   

Hey there!:

The stoichiometry of the reaction is:

TiO2 + 4 Cl2 + 3C =  CO2 + 2 CO +2 TiCl4

4 moles Cl2   2 moles TiCl4 
115 moles Cl2 moles TiCl4 ??

moles TiCl4 = 115 * 2 / 4 

moles TiCl4 = 230 / 4

=> 57.5 moles of TiCl4

Answer D

hope this helps!
