The reaction below can be used as a laboratory method of preparing small quantities of Cl₂(g). If a 62.6 g sample that is 98.5% K₂Cr₂O₇ by mass is allowed to react with 325 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?

Cr₂O₇^2- + H⁺ + Cl^- → Cr³⁺ + H₂O + Cl₂(g)     (not balanced)
