CrO42- (Chromate) Gram to mole Conversion:
To convert gram weight to mole we need to find first what is the molecular weight of CrO42- (Chromate). Suppose the molecular weight of CrO42- is M(CrO42-). Now we have to divide the gram weight by molecular mass of Chromate. Then the result gives us a mole number.
mole number of CrO42- (Chromate) = {(grams weight of CrO42-) ÷ Molecular mass of CrO42-}
= {w÷ M(CrO42-)} [suppose w is grams weight of Chromate ]
Example: Suppose a sample of CrO42- has 20.05 grams. Now we have to calculate the mole number of the CrO42-.
Ans: mole = (16.02 ÷ 115.99 )
= 0.13811535477196 mole of Chromate.

CrO42- (Chromate) mole to grams conversion:
If we know the mole number of Chromate and we want to calculate grams then we again need molecular mass of CrO42-. We know that the molecular mass of CrO42- is 115.99. To calculate grams we need to multiply mole numbers with molecular mass of Chromate. If molecular mass of CrO42- is M(CrO42-) and mole number is m(CrO42-) then
m(CrO42-) = (mole number of CrO42- × molecular mass )
= {m(CrO42-) × M(CrO42-)}
Example: A sample of CrO42- has 3.08 mole. We have to calculate how much grams of Chromate it equivalent is.
Ans: Here mole number of CrO42-, m(CrO42-) = 3.08
Molecular weight of CrO42-, M(CrO42-) = 115.99
So, gram weight = ( 3.08 × 115.99 )
= 357.2492 gram

How to Calculate Molecular Mass of Chromate (CrO42-):
For calculating molecular mass of Chromate we need atomic mass of chromium and oxygen. We know that atomic masses of chromium (Cr) and oxygen (O) are 51.996 and 15.9994 respectively. So molecular mass of Chromate = [atomic mass of chromium (Cr) + {atomic mass of oxygen (O) × 4}]
= { 51.996 + (15.9994 × 4)}
= 115.9936 gram
