Excess concentrated hydrochloric acid was added to 2.0g of potassium tetra oxo manganette (vii) and chlorine gas was evolved and collected as stp the equation of the reaction is below
2 kmno4 +16 HCl = 2 kcl+2 mncl2 +8H2O +5Cl2
1. calculate the number of moles of kmno4 used to prepare chlorine gas
2. The mass of potassium chloride used
3.the volume of chlorine gas produced at stp (k=39, Mn= 55,O=16, Cl=35, H=1 ) Avogadro's constant = 6.02×10^23,gaseous molar volume of stp = 22.4dm^3
