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.
Divide the number of moles by the number of liters. Now that you have the number of moles, you can divide this value by the number of liters of solution in order to find the molarity. 1  Example problem: molarity = moles of solute / liters of solution = 0.0215 mol / 5.2 L = 0.004134615.ivide the number of moles by the number of liters.
