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.
Calculations Using Standard Molar Volume. Standard Molar Volume is the volume occupied by one mole of any gas at STP. Remember that STP is Standard Temperature and Pressure. Standard temperature is 0 Â° C or 273 K. Standard pressure is 1 atmosphere or 760 mm Hg (also called torr). 1 mole of any gas at STP occupies 22.4 liters of volume.
