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.
Instructions. Determine the sodium hydroxide's concentration. This value will be printed on the solution bottle's label. For this example, imagine a solution of 1.5M NaOH. Convert the solution's volume to liters. If you have, for instance, 100 cubic centimeters of solution, divide by 1,000 -- 100 / 1,000 = 0.1 liters.Multiply the solution's molarity by its volume -- 1.5 x 0.1 = 0.15 moles.This is the number of moles of sodium hydroxide in the solution.nstructions.
