What is the molarity of a solution made by adding 1.565 moles of PbNO3 to 500 mL

[PbNO₃] = 3.13 M

Explanation:

Molarity is a specific sort of concentration where we have, the amount of solute's moles contained in 1 L of solution.

In this case, our solution's volume is 500 mL.

We convert to L → 500mL . 1L/1000 mL = 0.5L

Moles → 1.565 mol

Molarity (mol/L) → 1.565 mol / 0.5L = 3.13 M

There also types of concentration, for example molality which indicates the moles of solute in 1kg of solvent.

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.
