4 mole of a mixture of Mohr's salt and `Fe_2(SO_4)_3` requires `500mL` of ` 1 M K_2Cr_2O_7` for complete oxidation in acidic medium. The mole % of the Mohr's salt in the mixture is :

1 mole of equimolar mixture of ferric oxalate and ferrous oxalate requires x mole of KMnO_4 in acidic medium for complete oxidation. x is :

2 mole, equimolar mixture of Na_2C_2O_4 and H_2C_2O_4 required V_1L of 0.1MKHMO_4 in acidic medium for complete oxidation. The same amount of the mixture required V_2L of 0.2M NaOH for neutralization. The ratio of V_1 to V_2 is :

0.8 moles of a mixture of CO and CO_2 requires exactly 40 gram of NaOH in solution for complete conversion of all the CO_2 into Na_2 CO_3 . How many more of NaOH would for require for conversion into Na_2 CO_3 if the mixture (0.8 mole) is completely oxidised to CO_2 ?

A mixture of FeO and Fe_2 O_3 is completely reacted with 100mL of 0.25M acidified KMnO_4 solution. The resulting solution was then treated with Zn dust which converted Fe^(3+) of the solution to fe^(2+) . The Fe^(2=) required 100mL of 0.10MK_2 Cr_2O_7 solution. Find out the weight % Fe_2O_3 in the mixture.
