Answer
(a) 2.4 mol $PbO$, 2.4 mol $SO_{2}$
(b) 1.6 mol $PbO$, 1.6 mol $SO_{2}$
(c) 5.3 mol $PbO$, 5.3 mol $SO_{2}$
(d) 3.5 mol $PbO$, 3.5 mol $SO_{2}$
Work Step by Step
(a) $2.4\,mol\,PbS\times\frac{2\,mol\,PbO}{2\,mol\,PbS}=2.4\,mol\,PbO$
$2.4\,mol\,PbS\times\frac{2\,mol\,SO_{2}}{2\,mol\,PbS}=2.4\,mol\,SO_{2}$
(b) $2.4\,mol\,O_{2}\times\frac{2\,mol\,PbO}{3\,mol\,O_{2}}=1.6\,mol\,PbO$
$2.4\,mol\,O_{2}\times\frac{2\,mol\,SO_{2}}{3\,mol\,O_{2}}=1.6\,mol\,SO_{2}$
(c) $5.3\,mol\,PbS\times\frac{2\,mol\,PbO}{2\,mol\,PbS}=5.3\,mol\,PbO$
$5.3\,mol\,PbS\times\frac{2\,mol\,SO_{2}}{2\,mol\,PbS}=5.3\,mol\,SO_{2}$
(d) $5.3\,mol\,O_{2}\times\frac{2\,mol\,PbO}{3\,mol\,O_{2}}=3.5\,mol\,PbO$
$5.3\,mol\,O_{2}\times\frac{2\,mol\,SO_{2}}{3\,mol\,O_{2}}=3.5\,mol\,SO_{2}$
