preparation of K2Cr2O7 and related structure

In a titration experiment, 10 mL of an FeCI_2 solution consumed 25 mL of a standard K_2Cr_2O_7 solution to reach the equivalent point. The standard K_2Cr_2O_7 solution is prepared by dissolving 1.225 g of K_2Cr_2O_7 in 250 mL water. The concentration of the FeCI_2 solution is closest to [Given: molecular weight of K_2Cr_2O_7=294g mol^(-1)]

5.1 g sample of H_2O_2 solution containg x%H_2O_2 by weight requires x " mL of " K_2Cr_2O_7 solution for complete oxidation under acidic condition. What is the molarity of K_2Cr_2O_7 solution?

The n-factor for K_(2)Cr_(2)O_(7) in acidic medium is
