Chemistry - Mole Concept Question with Solution | TestHub

$12\mathrm{g}{\mathrm{K}}_2{\mathrm{CO}}_3$ was treated by a series of reagents so that all its carbon converted to $C{O}_2$. The resulting gas was then converted to carbonate ion and finally through a series of reactions , all the carbon converted to ${\mathrm{K}}_2{\mathrm{Zn}}_3{\left[\mathrm{Fe}(\mathrm{CN}{)}_6\right]}_2$. Calculate the weight of the product. [mol. wt. of K₂CO₃ = 138 and mol. wt. of K₂Zn₃ [Fe(CN)₆]₂ = 698]
