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.
V = volume. The Density Calculator uses the formula that density (p) is equal to mass (M) divided by volume (V) or p=M/V. The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
