Answer:
Moles = 8 moles
Solution:
Molarity is given as,
Molarity = Moles / Volume of Solution ------ (1)
Data Given;
Molarity = 2 M
Volume = 4 L
Solving eq.1 for Moles,
Moles = Molarity × Volume of Solution
Putting values,
Moles = 2 mol.L⁻¹ × 4 L
Moles = 8 moles
If water was nonpolar, life as it exists now would be impossible. Water is the means by which ionic substances ( Fe^3+, Na^+, Ca^2+, K^+, etc) and polar molecules are distributed around and in the cells of organisms.
<span>Water is a major contributor to erosion of mountains because of its polar nature. It is able to dissolve almost all minerals because of its attraction for the positive and negative parts of the minerals that it encounters. </span>
<span>If it was nonpolar, it would not exist in the solid and liquid state on earth. It is the attraction of the oppositely charged ends of different water molecules that makes it assume the liquid and solid state under the temperature ranges found on earth.</span>
Molecules in solids are packed a lot closer together than molecules in liquids and gases, so there is far less space between solid particles. Because of this, solid particles cannot move around quickly and freely like liquids and gases, instead they only vibrate so are fairly 'locked' into the same place, so solids have fixed volume and space.
