A sample of carbon monoxide at 57 degrees Celsius and under 0.75 atm occupies 85.3 liters of space. What mass of carbon monoxide is present in the sample?

Silica, sio2, is formed on silicon as an electrically insulating layer for microelectronic devices. silica is formed when silicon is exposed to o2 gas at an elevated temperature. at 900˚c, it takes 90 minutes for the oxygen to diffuse from the surface to form a 0.06 micron (0.06 x 10-6 m) thick layer of sio2 on
