1g atom of Ra^(226) is placed in an evacuated tube of volume 5 liter. Assuming that each ._(88)Ra^(226) nucleusis an alpha- emitterand all the contentsare present in tube, calculate the total pressure of gases and partial pressure of He collected in tube at 27^(@)after the end of 800 year. Neglect volume occupied by undecayed Ra.
