The decomposition of a certain mass of CaCO_(3) gave 11.2 dm^(3) of CO_(2) gas at STP. The mass of KOH required to completely neutralise the gas is |
|
Answer» 56 g `44//2=22g` `underset(56 g)(KOH)+underset(44 g)(CO_(2))to KHCO_(3)` KOH REQUIRED for complete NEUTRALISATION of 22 g `CO_(2)` is `(56)/(44)xx22=28 g`. |
