At a certain temperature the vapor pressure of pure heptane is measured to be .59 atm . Suppose a solution is prepared by mixing 85.9 of heptane and of acetyl bromide . Calculate the partial pressure of heptane vapor above this solution. Round your answer to significant digits. Note for advanced students: you may assume the solution is ideal.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.

alchemy hadn't scientific methods of study, appeal to mysticism and fantasy, the knowledge of chemistry and physics were modest at that time.

alchemy was - but as new rules were discovered it either changed into chemistry or it became "unscientific".
