They also are used for: 1  general anesthesia, 2  sedation prior to surgery or diagnostic procedures, 3  muscle relaxation,  alcohol withdrawal and drug associated 1  agitation, nausea and vomiting,  depression, 1  and. panic attacks.
Remember that 1 dm3 = 1 000 cm3 so the volume is also 12 000 cm3. The equation can be rearranged to find the number of moles, if the volume of gas at rtp is known: number of moles = volume of gas at rtp Ã· 24. Calculate the number of moles of hydrogen that occupy 6 dm3 at rtp. number of moles = 6 Ã· 24 = 0.25 mol.
To calculate molarity. 1  Find the number of moles of solute dissolved in solution. 2  Find the volume of solution in liters. 3  Divide moles solute by liters solution.ample Molarity Calculation. Take the following example: Calculate the molarity of a solution prepared by dissolving 23.7 grams of KMnO 4 into enough water to make 750 mL of solution. This example has neither moles or liters needed to find molarity. Find the number of moles of the solute first.
