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 molarity is equal to the number of moles of solute divided by the volume of the solution measured in liters. If you like to think of numbers and units instead of quantities look at the second version of the equation. In this equation x, y and z represent numbers: 2, 6 and 3 for example.t involves remembering that molarity is a relationship between moles and liters. 1.20. NaCl means there is 1.2 moles of NaCl per 1.00 liter of solution. We can use that as a conversion factor to set up the calculation that relates 400. ml (or .400 L) to the appropriate number of moles of NaCl.
