What is the formula between molarity and molality?
Molarity is defined as grams of solute dissolved in 1 liter of solution and molality is defined as grams of solute dissolvd in 1Kg of solvent
What is the formula relation between molality and molarity?
== Molality== (1000xMolarity)/((1000xdensity of solution)- (MolarityxMolecular weight of Solute)) ==
How are molarity and molality similar?
Both express moles of solute in the numerator.
What is the difference between molarity and molality?
The difference is in the denominators.Molarity (M) - the number of moles of solute divided by the number of liters of solution.Molality(m) - the number of moles of solute divided by the number of kilograms of solvent.
Molarity is to moles of solute over liters of solution as molality is to?
moles of solute over kg of solvent
Is it molality greater or molarity greater why?
"MolaRity" is the correct spelling for mass per amount solution."MolaLity" is the correct spelling for mass per amount solvent.The conversions of molality, b, to and from the molarity , c,for one-solute solutions are:c = ρ.b / [1 + b.M]andb = c / [ρ -c.M]where ρ is the mass density of the solution, b is the molality, and M is the molar mass of the solute.
What is a measure of the amount of solute dissolved in a solvent which is called?
Molarity (moles solute/L solvent) Molality (moles solute/kg solvent)
Why molality is better than the molarity concentration in chemisrtry pratical calculation?
Concentrations in molality (moles of solute per kilograms of solvent) are independent of temperature and pressure whereas concentrations in molarity (moles of solute per total volume of solution in liters) are not.
What is the formula of the molality of a solution?
The molality is the ratio between the mass of a solute (expressed in moles0 and the mass of the solvent (expressed in kilograms). The term is now anachronic.
Is Molarity is measured in the units of moles solutes solution?
Molarity (M) is moles of solute per liters of solution. In contrast, molality (m) is moles of solute per kilograms of solvent.
How do you find the mass percent mole fraction molality and molarity of a solution?
Mass percent = grams of solute/total grams of solution Mole fraction = mols component/total mols mix. Molarity = mols solute/L solution Molality = mols solute/kg solvent Hope this helps :)
What is the relation between the molarity and molality of an aqueous solution?
in molarity we dissolved no of moles of solute in 1 dm3 volume of its solution but in molality we dissolved no of moles of solute in 1000 gram or 1 kg of solvent in molarity we don't know the exact amount of solvent quantity but in mplality we know the exact volume of solvent ( water)
What is the of the amount of solute dissolved in a solvent called?
This is known as the concentration or more technically the molarity or molality of the solution.
How many ways are there to express the relative amounts of solute and solvent in solution?
- molarity- molality-percentage composition
What is the molarity of a solution containing 8.0 moles of solute in 4.2 kg of solvent?
The molality of this solution is 1,905; to calculate the molarity you need the density of the solution.
What word describe the measurement of how much solute dissolves in a given amount of solvent?
MolarityMolalityPercent composition
What is the definition for molality?
(chemistry) the concentration of a substance in solution, expressed as the number moles of solute per kilogram of solventmolality = moles of solute / kg of solvent
What is the 1 molarity of Na-OH?
Molarity:1.0 mol (NaOH) /L(solution) = 1.0 M NaOHThe conversions of molality, b, to and from the molarity , c,for one-solute solutions are:c = ρ.b / [1 + b.M]andb = c / [ρ -c.M]where ρ is the mass density of the solution, b is the molality, and M is the molar mass of the solute.
What measurement of the amount of solute is called?
it is expressed in molarity. if a mole of solute is dissolved in 1 liter of solution, the solution is said to be have concentration of 1M (M=molarity)
What concentration is expressed in terms of moles of solute per liter of solution?
This is the molarity.
What is the definition of molarity molality and normality?
Molarity is concentration in moles/L (symbolized by M). Molality is a different way of expressing molarity, but in moles of solute/mass of solvent in mol/kg (symbol m). Normality is molarity x number of equivalents (symbolized by N). Equivalents are the ions that it would dissociate into (H+, OH-, e-, etc.)
A concentration unit expressed in units of moles of solute per kilogram of solvent?
This is called molality.
What does molality measure?
concentration
What is the molality of a solution made by dissolving two moles of NaOH in 6 kg of water?
Molality is expressed as moles solute/kg solvent. Moles of solute = 2. Kg solvent = 6.Molality = 2 moles/6 kg = 0.33 molal
What does lower case m stand for in chemistry?
Probably molality (note: this is not a typo). Molality is the number of moles of solute per kilogram of solvent, and is not widely used except in equations dealing with colligative properties. Remember, molality is moles of solute/kg of solvent. It is always clear if you get this value correct because molality is ALWAYS higher than molarity. (This answer has been updated.)
