Molarity
Define molarity?
The molarity is defined as the total number of moles of solute present in a given solution per liter. It is read as “molar” and is represented by the letter “M,” and its unit is mol/L.
What is the formula of molarity for solution?
The formula to determine the Molarity of a solution is given as follows:
Molarity (M) = n / V
where,
“n” is the number of moles of the solute.
“V” is the volume of solution in liters.
What is the effect of temperature on molarity?
The molarity of a solution depends on the volume of the solution but not the volume of the solvent. As the volume of the solutions changes with the temperature change, the molarity of the given solution also gets affected by temperature. So, as the temperature increases, the volume of the solution increases, and as a result, the molarity of the solution decreases, and vice versa.
What is Gram equivalent?
The gram equivalent is defined by the amount or the mass of the substances that is utilized to displaces a fixed amount of another substance.
Molarity – Definition, Formula and Solved Examples
Molarity is defined as total number of moles of solute per litre of solution. It is represented by M. In chemistry, the molarity is one of the concentration units. The concentration of solutions can be expressed more effectively using measurements based on moles. The SI unit of Molarity is Mole.
Molarity
A mole is an SI unit that measures the amount of a substance, where the amount of a substance is a measurement of the number of its elementary entities present in an object or sample. According to the definition, a mole contains exactly 6.022 × 1023 elementary entities, where 6.022 × 1023 is called Avogadro’s number (NA). Molarity is used to measure the concentration of a solution, where a concentrated solution is a solution with more solute and less solvent.
