# Matter wavelength and indeterminate of location and energy

I have to find matter wavelength and indeterminate of location and energy for hydrogen particle which is in gas with konwn p, V, T

I'm sorry for my english skills:P

pressure will be $$p_{g}$$

$$\lambda = \frac{h}{p}$$

$$p = mv$$

$$v = \sqrt{\frac{3p_{g}}{\varrho}}$$

$$\varrho = \frac{n\mu}{V}$$

$$p_{g}V = nRT$$

$$\varrho = \frac{p_{g}\mu}{RT}$$

$$v = \sqrt{\frac{3RT}{\mu}}$$

$$\lambda = \frac{h}{m\sqrt{\frac{3RT}{\mu}}}$$

m - mass of hydrogen particle, $$\mu$$ mass of gas particle

Am I doing it correctly so far?
