In how many grams of water should 25.31 g of potassium nitrate (KNO3) be dissolved to prepare a 0.1982 m solution?
Added by Jacqueline L.
Step 1
The molar mass of KNO3 is calculated by adding up the atomic masses of each element in the compound. Molar mass of K = 39.10 g/mol Molar mass of N = 14.01 g/mol Molar mass of O = 16.00 g/mol (there are three oxygen atoms in KNO3) So, the molar mass of KNO3 = Show more…
