Question

Define in a paragraph the term mole, and explain how this metric unit relates to the molor Concentration of a Solution

Answer 1

Mole is defined as the SI unit for the amount of a substance. One mole has a mass of 6.022 x 1023 particles of the substance. This numerical value is also known as Avogardros's constant as it is the number of elementary particles like atoms, molecule or compounds per mole of a substance. So, to find the number of moles in a substance, divide the number of atoms by the Avogardo's number.

Molar concentration of a solution is known as the Molarity of a solution. The Molarity is directly proportional to mole. That means, if the moles in a solute increases, Molarity also increases and vice versa. So, to find the Molarity of a solution, divide the number of moles of solute by the Volume of solution in liter.
