Molarity Practice Problems #1 - WordPress
PDF fileMolarity Practice Problems #1 – Answer Key 1) How many grams of potassium carbonate are needed to make 280 mL of a 2.5 M solution? Using the molarity equation (M = mol/L), we can find that we'll need 0 mol of potassium carbonate. Given that the molar mass of K2CO3 is 138 g/mol, this means that we'll require 97 grams
ChemTeam: Molarity Problems #1 - 10
A teacher might teach problems where the molarity is calculated but ask for the volume on a test question. Note: Make sure you pay close attention to multiply and divide. For example, look at answer #8. Note that the 58 is in the denominator on the right side and you generate the final answer by doing 0 times 0 times 58.
