I recently got the following question, for some reason i can't seem to get the correct answer-
"For 25g of each of the following reactants, how many grams of CrSO4 will result?
4Zn + K2Cr2O7 + 7H2SO4 ---> 4ZnSO4 + 2CrSO4 + K2SO4 + 7H2O
I tried it twice and got either 12.6 or 25.2
Both answers are wrong, i can't figure out why. Any help would be much appreciated
