Volume goes down, pressure goes up. p = 1.0 atm x ( 5.0L/2.0L) = 2.5 atm. Convert that to psi.

math help
could some one please explain to me reciprocal how to find the reciprocal my math home work says find the reciprocal of (-1/8)(13/2)(4) reciprocal you change over so is the -1/8 -8/1 or would it be 8/1 13/2 would be 2/13 4 would be 4/1 then 1/4 then i would multiply all ...

chemistry
Total pressure is 755.2 as measured by the barometer. The total is composed of two partial pressures; i.e., that of the H2 gas + the water vapor at 22 C. Ptotal = PH2 + PH2O. You can look up the vapor pressure of water in tables at various temperatures to find PH2O, then ...

Based on what you told me (I've not performed this experiment), PV = nRT so R = (PV)/nT If you did not correct the pressure you read for the room for the vapor pressure of water (don't you usually subtract the vapor pressure of water to obtain the partial pressure of the dry ...
