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.
Standard molar volume of a gas is the volume occupied by 1 mole of any gas at 273 K and 1 atmospheric pressure (STP). It is equal to 22.4 liters of 22,400 ml.It is the same for all gases. S.T.P.olar volume is considered to be the volume occupied by one mole of any gas at a given pressure and temperature. This is denoted by V m. The Molar volume unit is found to be litre per mole or milliliter per mole.
