Mass in gram of 2.74 moles of KMnO4 |
|
Answer» Molecular WEIGHT of KMnO4 is [39+55+(16×4)], which is equal to 158grams158grams of KMnO4 contains 55GRAMS of Potassium. (ATOMIC weight of Potassium is 55grams)40grams of KMnO4 contains 15855∗40, which is almost equal to 14grams of PotassiumNow,55grams of Potassium equals to 1mole of Potassium1gram of Potassium equals to 551mole of PotassiumThus, 14grams of Potassium equals to 551∗14mole of Potassium, which is almost equal to 0.25mole of Potassium |
