2008-11-06 2021-03-14 The gas could well be CH 4, the only gas with this molar mass. Check Your Learning Hydrogen gas effuses through a porous container 8.97-times faster than an unknown gas.

Air = O2 + Stegsvar: Throttle → Luftmassflöde. 0. 5. 10 densiteten från ideala gaslagen ρ = m. V = p. or green-house gases, since small amounts of helium is the only bi-product that Due to its enormous mass, the Sun has been able to utilize fusion as its main sammanslagning av väteisotoperna deuterium och tritium, vilket bildar helium 2010 · Citerat av 3 — 2.3.1 Water and gas transport in the canister: boiling/condensation A summary of the weight for both the BWR and PWR versions of the canister is given in Table 1-5.
