Question 52

In an industrial process, pure silicon tetrachloride, $SiCl4\text{SiCl}_4$ , is reacted with 600 moles of magnesium (an excess).

\text{SiCl}_4 + 2\text{Mg} \rightarrow \text{Si} + 2\text{MgCl}_2

Calculate the number of moles in 34 000 grams of silicon tetrachloride.

Relative atomic masses ( $A_r$ ): $Cl=35.5\text{Cl} = 35.5$ , $Si=28.0\text{Si} = 28.0$
