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.
The volume of one mole of gas is called the molar gas volume. The volume of gas produced in a chemical reaction can be measured by collecting it over water.Letâs discuss the determination of the molar volume of gas and its applications.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.
