Converting Between Concentration Units

Molarity and Molality . Often a laboratory will provide you with the concentration of the solution in molarity, but ... Step 3: Now you need to determine how many grams of H 2 SO 4 were present. You assumed you have 1 L of solution, so that means you have 18 moles of H 2 SO 4. Convert 18 moles of H 2 SO 4 to grams. ................
