Oratories - Review Part C: Stoichiometric calculations. Show your calculation procedures. Without calculations you will receive no credit for the work, even if the response is correct. For both reactions given in Part B, you are given 3.00 g of each reactant. Based on this information wwer the following questions: 1) Calculate the molar mass of all chemicals in the reactions, Al = 20 Cr-52 N2=28 Cr2O3 = 152 MHz=17 th=2 Al2O3 = 102 2) Using stoichiometric calculations determine which chemical is the limiting reactant and which one is excess reactant. 162 was ZAI + Cr2O3Al2O3 +20 H + 3H22NH3 Oratories - Review Part C: Stoichiometric calculations.
