The wastewater solution from a factory containing high levels of salts needs to be diluted before it can be released into the environment. therefore, two containers of waste solution are separated by a semipermeable membrane and pressure is applied to one container, forcing only water molecules through the membrane and diluting the waste solution in the other container. as dilution continues, higher and higher pressures are needed to counteract the natural tendency for the water molecules to have a net flow back toward the more concentrated solution. what was the applied pressure at the end of this process if the final concentrations of the solutions were 0.053 m and 0.170 m at a temperature of 23 ∘c?

The applied pressure at the end of this process is P = -2.859atm

Explanation:

Write down the given values

there are concentration of two solutions

S1 = 0.053 M

S2 = 0.170 M

Temperature (T) = 23°C

that is written as 298 K

it can be solved by multiplying ans subtracting the values

P=MR1-MR2

0.053 M * 0.082 * 298 - 0.170 M * 0.082 * 298

= 1.295 - 4.15412

P = -2.859atm

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.
