A sample of hydrogen gas was collected over water at 36°C and 855 mm Hg. The volume of the container was 6.50 L. Calculate the mass of H2(g) collected. (Vapor pressure of water = 44.6 torr at 36°C)
Infrared Spectroscopy Lab 1) Why must a sample for IR be dry. 2) How will the spectrum be affected if a background scan is omitted or improperly obtained. 3) The stretching from C-C single bonds is virtually invisible to IR . Why
