K2Cr2O7 (Potassium dichromate) Gram to mole Conversion:
To convert gram weight to mole we need to find first what is the molecular weight of K2Cr2O7 (Potassium dichromate). Suppose the molecular weight of K2Cr2O7 is M(K2Cr2O7). Now we have to divide the gram weight by molecular mass of Potassium dichromate. Then the result gives us a mole number.
mole number of K2Cr2O7 (Potassium dichromate) = {(grams weight of K2Cr2O7) ÷ Molecular mass of K2Cr2O7}
= {w÷ M(K2Cr2O7)} [suppose w is grams weight of Potassium dichromate ]
Example: Suppose a sample of K2Cr2O7 has 296.72 grams. Now we have to calculate the mole number of the K2Cr2O7.
Ans: mole = (295.54 ÷ 294.185 )
= 1.0046059452385 mole of Potassium dichromate.

K2Cr2O7 (Potassium dichromate) mole to grams conversion:
If we know the mole number of Potassium dichromate and we want to calculate grams then we again need molecular mass of K2Cr2O7. We know that the molecular mass of K2Cr2O7 is 294.185. To calculate grams we need to multiply mole numbers with molecular mass of Potassium dichromate. If molecular mass of K2Cr2O7 is M(K2Cr2O7) and mole number is m(K2Cr2O7) then
m(K2Cr2O7) = (mole number of K2Cr2O7 × molecular mass )
= {m(K2Cr2O7) × M(K2Cr2O7)}
Example: A sample of K2Cr2O7 has 3.043 mole. We have to calculate how much grams of Potassium dichromate it equivalent is.
Ans: Here mole number of K2Cr2O7, m(K2Cr2O7) = 3.043
Molecular weight of K2Cr2O7, M(K2Cr2O7) = 294.185
So, gram weight = ( 3.043 × 294.185 )
= 895.204955 gram

How to Calculate Molecular Mass of Potassium dichromate (K2Cr2O7):
For calculating molecular mass of Potassium dichromate we need atomic mass of potassium, chromium and oxygen. We know that atomic masses of potassium (K), chromium (Cr) and oxygen (O) are 39.0983, 51.996 and 15.9994 respectively. So molecular mass of Potassium dichromate = [{atomic mass of potassium (K) × 2} + {atomic mass of chromium (Cr) × 2} + {atomic mass of oxygen (O) × 7}]
= {(39.0983 × 2) + (51.996 × 2) + (15.9994 × 7)}
= 294.1844 gram
