Assuming you mean 2.00 M and not 2.00 m, then moles of sodium chromate would be as follows:1.75 L x 2.00 moles/L = 3.50 moles sodium chromate
Na2CrO4 is sodium chromate.
Li2Cr2O7 - lithium dichromate
Sodium Chromate
The chemical formula of sodium chromate is Na2CrO4. The sodium cation is Na+ and the chromate anion is (CrO4)2-.
Na2Cr2O7 (the formula is not Na2CrO7) is sodium dichromate. Na2CrO4 is sodium chromate.
Sodium chromate = Na2CrO4
Na2CrO4 is sodium chromate.
Li2Cr2O7 - lithium dichromate
Sodium dichromate has the formula Na2Cr2O7.
Na2CrO4
it is 106 grams it is 106 grams it is 106 grams
Sodium Chromate
The chemical formula of sodium chromate is Na2CrO4. The sodium cation is Na+ and the chromate anion is (CrO4)2-.
Na2Cr2O7 (the formula is not Na2CrO7) is sodium dichromate. Na2CrO4 is sodium chromate.
Na2CrO4 (aq) + 2LiOH (aq) -----> Li2CrO4 (s) + 2NaOH (aq)
That's sodium chromate. However, the correct formula would actually be Na2CrO4, because sodium is a +1 metal, and the chromate polyatomic has a -2 charge. Therefore it will require two sodium atoms.
4 molecules It's Na2CrO4 · 4H2O
