Calculate the root mean square speed of 1 mole of hydrogen molecules at 253k. Neglet the mass of electron |
|
Answer» Molar mass of hydrogen gas, M = 2 x 10-3kg/mol R = 8.34 universal gas constant. root mean square velocity Vrms = \(\sqrt{\frac{3RT}{M}}\) = \(\sqrt{\frac{3\times 8.31\times 253}{2\times 10^{-3}}}\) = \(\sqrt{3153.64\times 10^3}\) = \(\sqrt{315.36\times 10^4}\) Vrms = 17.75 x 102m/s |
