species to its proper component material balance written below:

Note: Only four of the following material balances listed will be used!

$M_A$ is the molar mass of $A.$

$a,b,c$ are the positive stoichiometric coefficients from Question $1.$

$(0\mathrm{.}158)**(303)=a{}^{}$

$0=(0\mathrm{.}158)**(303)-M_{Mg}(a{}^{})$

$0=w_{MgC{l}_{2,2}}**m_2^{}+M_{MgC{l}_2}(c{}^{})$

$0=-w_{Si,2}**m_2^{}+M_{Si}(b{}^{})$

$0=(0\mathrm{.}842)**(303)-w_{SiC{l}_{4,2}}**m_2^{}-M_{SiC{l}_4}({}^{})$

$2**w_{Si,2}**m_2^{}=M_{Si}(b{}^{})$

$0=-w_{MgC{l}_{2,2}}**m_2^{}+M_{MgC{l}_2}(c{}^{})$
