What happens to molarity when a solution is diluted?

Diluting a sample will reduce the molarity. For example if you have 5mL of a 2M solution which is diluted to a new volume of 10mL the molarity will be reduced to 1M.

Is it possible for molarity and molality to be the same?

Although their spellings are similar, molarity and molality cannot be interchanged. Molarity is a measurement of the moles in the total volume of the solution, whereas molality is a measurement of the moles in relationship to the mass of the solvent.

Does molality change with dilution?

On diluting solution, its normality and molarity changes but molality remains constant.

At what conditions molarity is equal to molality?

For an aqueous solution, molarity and molality should be almost equal when the concentration is very low.

For what type of solution molarity and molality of a solution are nearly same?

Molality and molarity of a solution are identical for very dilute solution. i.e having higher amount of water as solvent. Example : Very less amount of NaOH in high amount of around 500 g water will have same value of Molality and molarity due to presence of high amount of water .

What is molarity and molality give the differences of molarity and molality that make molality is more suitable to be used in Colligative properties explain?

Molality differs from molarity only in the denominator. While molarity is based on the liters of solution, molality is based on the kilograms of solvent. Concentrations expressed in molality are used when studying properties of solutions related to vapor pressure and temperature changes.

When molarity of solution becomes equal to its molarity?

Molality is defined as the no. of moles of solute per kilogram of solvent. Because the density of water at 25°C is around 1kg/litre thus the molality is approximately equal to molarity for dilute aqueous solutions at thistemperature.

What is molarity and molality give the differences of molarity and molality that make molality is more suitable to be used in Colligative properties?

Why molality is preferred over molarity in expressing the concentration of a solution by a scientist?

Molality is preferred over molality as molality takes mass of solution but molarity takes volume of solution which changes with change in temperature. Because molality is temperature independent whereas other concentration terms like molarity depend on volume of the solution with varies with temperature.

In which condition normality and molarity of a substance becomes equal?

For some chemical solutions, Normality and Molarity are equivalent or N=M. This typically occurs when N=1.

Why do molality and molarity of dilute aqueous solutions differ very little?

The molality and molarity of dilute aqueous solutions differ very little because the density of water is 1.0gcm−3at room temperature. Due to this, the volume of solution will be approximately equal to the mass of solvent. Thus, both Assertion and Reason are correct and Reason is the correct explanation for Assertion.

What is the difference between molarity and mass?

Molarity is “moles of solute divided by the volume of the solution, usually in L”. In the calculations concerning equilibria in aqueous solutions (and therefore pH calculations as well) , the concentrations of the intervening species are reported as molarities. Masses are strictly additives, volumes are not.

What happens to solute and solution in a very dilute solution?

In very dilute solution the amount of solvent is too large as compared to amount of solute. so the amount of solution is nearly equal to amount of solvent. ∴ statement I is correct.

What is the molarity and molality of 1 kg of sucrose?

Example : 1 L of the solution contains 0.0001 M Sucrose. If we assume that the density of the solution is almost equal to that of pure water (1 kg/L), then we find that 1 L of solution will weigh 1 kg. If 1 kg of solution contains 0.0001 M of sucrose , then it is 0.0001 m in sucrose, so the molarity and molality are almost the same.
