Answer to Question #174457 in General Chemistry for Mahmoud Sherry

Question

In a certain industrial operation 3.54 × 107 g of TiCl4 are reacted with 1.13 × 107 g of Mg.

(a)Calculate the theoretical yield of Ti in grams.

(b)Calculate the percent yield if 7.91 × 106 g of Ti are actually obtained.

Answer 1

TiCl4 + 2Mg = 2MgCl2 + Ti

TiCl4 is the limiting reagent

TiCl4 = Ti

190g TiCl4 = 48g Ti

3.54 × 10⁷ TiCl4 = (48 × 3.54 ×10⁷ )/ (190)

= 8.94 ×10⁶g

% yield = actual yield/ theoreectical yield ×100%

= 7.91 ×10⁶ / 8.94 ×10⁶ × 100%

= 88.47%
