Question 983122:  A mixture of nitrogen,oxygen,and helium contains 0.25 ,0.15 and 0.4 respectively if d pressure cionsituted by oxgen is 2.5 atmosphere find partial pressure of helium? 
 Answer by KMST(5328)      (Show Source): 
You can  put this solution on YOUR website! Where are the units for 0.25 ,0.15 and 0.4?
 
 
If a mixture of nitrogen, oxygen, and helium contains 0.25, 0.15 and 0.4   respectively, 
and the partial pressure of oxygen is 2.5 atmosphere, 
then the partial pressure of helium is   {rounded to a reasonable number of significant digits).
 
 
If the mixture of nitrogen, oxygen, and helium contains 0.25, 0.15 and 0.4   respectively, 
the answer is   too.
 
 
If the mixture of nitrogen, oxygen, and helium contains 0.25, 0.15 and 0.4   respectively, 
then the number of moles is 
  for oxygen, and 
  for helium, 
and the partial pressure of helium is
