Cis-platin $\left[\mathrm{Pt}{\left({\mathrm{NH}}_3\right)}_2{\mathrm{Cl}}_2\right]$, a compound used in cancer treatment is prepared by reaction of ammonia with potassium tetrachloro platinate.

${\mathrm{K}}_2{\mathrm{PtCl}}_4+2{\mathrm{NH}}_3⟶2\mathrm{KCl}+\mathrm{Pt}{\left({\mathrm{NH}}_3\right)}_2{\mathrm{Cl}}_2$

(P) How many grams of cis-platin are formed from 41.5 g ${\mathrm{K}}_2{\mathrm{PtCl}}_4$ and $34 gm {\mathrm{NH}}_3$ if the reaction takes place in 90 % yield? [ Ans = (x)]

(Q) What is the maximum mass of $\mathrm{KCl}$ which can be produced if initially total 9 moles of reactant are taken. Assuming 100 %  reactions. [Ans (y)]
[Write the value of $(x+y),(\mathrm{Pt}=195)$ ]
