1. A 36.0-L cylinder of a gas used for calibration of blood gas analyzers in medical laboratories contains 350 g of CO2, 805 g of O2, and 4880 g of N2. At 25 °C, what is the pressure in the cylinder in kilopascals? Please show the equation used to find the answer.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
