Final answer:
To prepare a 1 molar solution of KNO3 (potassium nitrate), dissolve 101.1 grams in enough water to make a total volume of 1 liter.
Step-by-step explanation:
To prepare a 1 molar solution of KNO3 (potassium nitrate), you need to dissolve one mole of KNO3 in enough water to make a total volume of 1 liter. The molar mass of KNO3 is 101.1 g/mol.
So, to prepare a 1 molar solution, you would need 101.1 grams of KNO3 dissolved in enough water to make a final volume of 1 liter.
