Achemist prepares a solution of silver nitrate by measuring out of silver nitrate into a volumetric flask and filling the flask to the mark with water. calculate the concentration in of the chemist's silver nitrate solution. round your answer to significant digits.

Amount of silver nitrate taken = 269.μmol

Volume of the solution = 300. mL

Concentration of a solution is generally expressed in terms of molarity. Molarity is defined as the moles of a substance present per liter of the solution.

We want the concentration in millimoles/L.

Converting μmol to millimol solute:

μ = 0.269 millimol

Volume from mL to L:

Therefore concentration of the chemist's solution =

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.
