=0.12molAlCl_3=0.12molAlCl3

Explanation:

  1. Since data are already in moles, find the the required moles of each substanced considering a complete reaction to find the limiting reactant; i.e.,
    A. etaAl=0.15molA.ηAl=0.15mol
    =0.15cancel(molAl)xx(6molHCl)/(2cancel(molAl))
    =0.45molHCl

"This means that:"
0.15molAl-=0.45molHCl

"Therefore"

(etaHCl " available")/(=0.35molHCl)<(etaHCl " required")/(=0.45molHCl)

B. etaHCl=0.35mol
=0.35cancel(molHCl)xx(2molAl)/(6cancel(molHCl))
=0.12molAl

"This means that:"
0.35molHCl-=0.1167molAl

"Therefore"

(etaAl " available")/(=0.15molAl)>(etaAl " required")/(=0.12molHCl)

  1. Thus, the limiting reactant is HCl. Now. find the AlCl_3 formed; i.e.,
    =0.35cancel(molHCl)xx(2molAlCl_3)/(6cancel(molHCl))
    =0.12molAlCl_3
