limiting

Post by Laila Camila »

In a beaker: 15.0 g of oxalic acid with 15.0 g of potassium permanganate and 15.0 g of hydrochloric acid were added. What is the limiting reagent in this reaction?
2 KMNO 4 (aq) + 5 H 2 C 2 O 4 (aq) + 6 HCl (g)  2 MnCl 2 (aq) + 2 KCl (aq) + 10 CO 2 (g) + 8 H 2 O (l )

You have the ratio 2: 5: 6

Convert each 15 g to the mol by using molar mass

Compare the ratio. The lowest number is the limiting reagent.
