IF YOU ANSWER THIS IL ANSWER YOUS AND YOU GEST 10PTS FOR BEST ANSWER .) PLEASE I really need this tonight.....

please answer these you dont have to answer all if you cant but please attemt!!!!!
please .)
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).
TiO2(s) + C(s) + 2 Cl2(g) TiCl4(s) + CO2(g)
(a) What mass of Cl2 gas is needed to react with 1.82 mol TiO2?
g

(b) What mass of C is needed to react with 1.82 mol of TiO2?
g

(c) What is the mass of all the products formed by reaction with 1.82 mol of TiO2?
g

Ethanol (C2H5OH) is produced from the fermentation of sucrose in the presence of enzymes.
C12H22O11(aq) + H2O(g) 4 C2H5OH(l) + 4 CO2(g)
Determine the theoretical yield and the percent yields of ethanol if 735 g sucrose undergoes fermentation and 314.5 g ethanol is obtained.

(a). 1.82 mol TiO2 needs 1.82 x 2 = 3.64 mol Cl2.
Mass Cl2 = 3.64 x 71 = 258.44g
(b). 1.82 mol C needed = 1.82 x 12 = 21.84g
(c). TiO2 = 48+32 = 80g. 1.82 mol = 145.6g
Mass products = mass reactants = 145.6 + 21.84 + 258.44 = 425.88g
