The reaction below can be used as a laboratory method of preparing small quantities of Cl2(g) . Cr2O2−7+14H++6Cl−→2Cr3++7H2O+3Cl2(g) If a 50.6- g sample that is 98.5 % K2Cr2O7 by mass is allowed to react with 345 mL of HCl(aq) with a density of 1.15 g/mL and 30.1 % HCl by mass, how many grams of Cl2(g) are produced?
