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.
If it starts at 2.50 mL, subtract that from the final reading, which was 32.08 mL. 32.08 - 2.50 = 29.58 mL titrant (0.31 M NaOH). b) If we got 29.58 mL of 0.31 NaOH-we need to do math to determine the moles. Remember, M = mol/L. So 0.31 = mol/ 0.02958 L. Moles then = 0.00917 moles.
