Determine the numbers of grams of H20 are formed by the complete reaction of 100g K2Cr2O7 and determine the numbers of grams of K2Cr2O7 are essential to form the 50g CrCl3?
The reaction is K2Cr2O7 + 3Na2SO4 + 8HCl----2KCl +3Na2SO4+2CrCl3 + 4H2O
The FW of K2Cr2O7 294.2g/mole
The FW of CrCl3 is 158.4g/mole
The FW of H2o is 18g/mole
