Calculate the weight of `MnO_(2)` required to react with `HCl` having specific gravity `1.2gm//ml`. `4%` by mas necked to produc

Correct Answer - 8
`MnO_(2)+4HClto MnCl_(2)+Cl_(2)+2H_(2)O`
`100gm` sol contains `4gm HCl`
`100/1.2 ml` sol contains `4 gm HCl`
`nCl_(2)=1.8/22.4=0.0805`
`W_(MnO_(2))=0.0805xx87=8gm`

Calculate the weight of `MnO_(2)` required to react with `HCl` having specific gravity `1.2gm//ml`. `4%` by mas necked to produce `1.8L` of `Cl_(2)` a
