What volume of a 1.2 M solution of Na2CO3 can be made from 800 ml. of a 1 point
4.2 molar solution of this solute? (answer in Liters)

V₂ = 2.8 L

Explanation:

Given data:

Initial volume = 800 mL ( 800/1000 = 0.8 L)

Initial molarity = 4.2 M

Final volume = ?

Final molarity  = 1.2 M

Solution:

Formula:

M₁V₁ = M₂V₂

M₁ = Initial molarity

V₁ = Initial volume

M₂ = Final molarity

V₂= Final volume

M₁V₁ = M₂V₂

4.2 M × 0.8 L  = 1.2 M× V₂

3.36 M.L =  1.2 M× V₂

V₂ = 3.36 M.L/1.2 M

V₂ = 2.8 L

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.
