Conductivity is the conductance per unit volume of the solution; it may also be considered as the concentration of ions per unit volume of solution. Molar Conductivity is the conductance of the entire solution having 1 mole of electrolyte dissolved in it.

At standard Temperature and Pressure (STP) the molar volume (Vm) is the volume occupied by one mole of a chemical element or a chemical compound. It can be calculated by dividing the molar mass (M) by mass density (ρ). Molar gas volume is one mole of any gas at a specific temperature and pressure has a fixed volume.

An important distinction between molality and molarity is the difference between a solution and a solvent. Molarity is the ratio of the moles of a solute to the total liters of a solution. ... Molality, on the other hand, is the ratio of the moles of a solute to the kilograms of a solvent.

Use the titration formula. If the titrant and analyte have a 1:1 mole ratio, the formula is molarity (M) of the acid x volume (V) of the acid = molarity (M) of the base x volume (V) of the base. (Molarity is the concentration of a solution expressed as the number of moles of solute per litre of solution.)

Metallic conductance involves the movement of electrons throughout a metal. Electrolytic conduction involves the movement of ions throughout a pure liquid or solution. The major difference between them is that one involves the movement of electrons and the other involves the movement of ions.

Variation of Molar Conductivity with Concentration: Due to an increase in dilution degree of dissociation increases and which results in an increase in the molar conductivity. For the strong electrolyte, the molar conductivity increases sharply with increasing concentration.

Molarity ( ) is defined as the number of moles of solute per liter of solution. Molality ( ) is defined as the number of moles of solute per kilogram of solvent. Normality ( ) is defined as the number of equivalents per liter of solution.

There is no direct connection between the molar mass of a compound and its vapor pressure. The vapor pressure of a liquid at a particular temperature depends on the strengths of the intermolecular forces.

Conductivity uses SI units, Conductance uses Imperial units. ... Thermal conductance deals with heat loss. Thermal Conductance deals with composite material.

Key Points Molar heat capacity is a measure of the amount of heat necessary to raise the temperature of one mole of a pure substance by one degree K. Specific heat capacity is a measure of the amount of heat necessary to raise the temperature of one gram of a pure substance by one degree K.

The key difference between conductivity and molar conductivity is that conductivity is the measure of the ability of an electrolyte to conduct electricity whereas the molar conductivity is the conductivity of an electrolyte measured per unit molar concentration.

Here is an example of directly using the Beer's Law Equation (Absorbance = e L c) when you were given the molar absorptivity constant (or molar extinction coefficient). In this equation, e is the molar extinction coefficient. L is the path length of the cell holder. c is the concentration of the solution.

A certain amount of univalent ions provides the same amount of equivalents while the same amount of divalent ions provides twice the amount of equivalents. For example, 1 mmol (0.001 mol) of Na+ is equal to 1 meq, while 1 mmol of Ca++ is equal to 2 meq.

The relation between solubility and the solubility product constants is that one can be used to derive the other. In other words, there is a relationship between the solute's molarity and the solubility of the ions because Ksq is the product of the solubility of each ion in moles per liter.

Concentration is the ratio of the amount of solute per amount of solution. Molarity is a unit of concentration that specifically relates the number of moles of a solute per liter of solution.

Molarity vs molality. An important distinction between molality and molarity is the difference between a solution and a solvent. Molarity is the ratio of the moles of a solute to the total liters of a solution. ... Molality, on the other hand, is the ratio of the moles of a solute to the kilograms of a solvent.
