- 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 ÷ 24. Calculate the number of moles of hydrogen that occupy 6 dm3 at rtp. number of moles = 6 ÷ 24 = 0.25 mol.

How do you calculate mass using density and volume? Density is the mass per unit of volume of a substance. The density equation is: #Density# = #Mass/Volume#. To solve the equation for Mass, rearrange the equation by multiplying both sides times Volume in order to isolate Mass, then plug in your known values (Density and Volume). Then solve for Mass. #Mass# = #Density x Volume#.
