The name for K2Cr2O7 is potassium dichromate.
That is potassium dichromate (or it would be, if the sub-scripts were written correctly).
Potassium Dichromate
Potassium Dichromate (VI)
potassium dichromate
Potassium chronium oxide
Potassium heptaoxochromate(vi)
You can get the Atomic Masses in a periodic table: K = 39,1u; Cr = 52,0u; O = 16,0u. Then do de sum: (39,1*2+52*2+16*7) = 294,2u The concept on Formula Mass is similar to the Molecular Mass, but applied to a ionic compound.
your name! lol i have heard this riddle dozens of times b4.

1N of k2cr2o7=49.09 gm/1 L 0.25N=12.2725 gm of k2cr2o7 in 1 L of water.
The chemical formula of potassium dichromate is K2Cr2O7
Potassium dichromate has a molar mass of 294.19 g/mol and contains 2 atoms of potassium. This means one mole of potassium dichromate contains 294.19 * 2 = 588.38 grams of potassium. Therefore, 12.5 grams of potassium dichromate would contain 12.5 * 2 / 294.19 ≈ 0.085 grams of potassium.

No, molarity and normality are not the same in K2Cr2O7. Molarity is the concentration of a solution expressed in moles of solute per liter of solution, while normality is a measure of concentration based on the equivalents of a solute in a solution. In the case of K2Cr2O7, as it has more than one ion that can undergo reaction, the normality would be different from the molarity.
There is no reaction between H2O2 and K2Cr2O7 because both are oxidants.
