Webmore. So if we began with the ideal gas law and wanted to solve for volume, that would indeed be the equation we would use: V = (nRT)/P. However this use with just using this equation is that we don't just want to calculate volume at a single state, we want to calculate the volume at a new second state.
WebAnswer. At standard temperature and pressure ( 0 ∘ C and 1 atm ), one mole of gas will occupy 22.4 litres. This is true regardless of the gas being used. As volume and the amount of moles of a gas are directly proportional, two moles of any gas at STP should have double the volume as one mole: 2 2. 4 1 × 2 = 4 4. 8. Web11 apr. 2024 · 1 mol = 6.022x10 23 molecules/mole. Therefore 1 molecule = (28.0134 g/mole) / (6.022x10 23 molecules/mole) = 4.6517x10 -23 grams = 4.6517x10 -26 kg. And then I took the average density of the atmosphere between 0 and 80 km that I calculated using a 1976 Technical Report by NASA, which resulted to be 0.13523 kg/m 3 and …
