How many liters of Cl2 has at a pressure of .950 atm and a temperature of 298K will be collected from the reaction of 25 mL of a .100 M aqueous solution of KMnO4 and an excess of HCI?

Question

KMnO4+HCI->MnCl2+Cl2+H2)+KCl

Answer 1

mols KMnO4 = M x L = ?
Use simple stoichiometry to convert mols KMnO4 to mols Cl2, then use PV = nRT and solve for V (in L).
