nid404:
I need help with one more question...
Actually i don't know the formulae for finding out partial pressure...wet and dry gas and stuff....cuz i joined classes late
1) Oxygen is collected over water at 20 degrees Celsius . The pressure inside is shown by the gas is 740mm of Hg. What is the pressure of O2 alone if V.P of H2O is 18mm at 20 degrees celsius
do u simply do 740mm-18mm?? Please help

Exactly
