Is molality or molarity expressed in grams of solute instead of moles of solute?
Molarity is a measure of the concentration of a solution, and therefore cannot be said to be just moles.It is in fact moles per litre (mol/L), or molars.
What quantity represents the ration of the number of moles of solute per kilogram of solvent?
Mol is a cocentration unit !
How many ways are there to express the relative amounts of solute and solvent in solution?
- molarity- molality-percentage composition
What is the molality of a solution of ZnSO4 whose density is 1.25 g per ml and whose molarity is 1.19M?
1.12 m
What does molarity M measure in a solution?
Concentration
How are concentrations in solutions quantified?
through molarity,molality, normality. through molarity,molality, normality.
When does molarity and molality become equal?
In dilute solutions... ie closer a solution is to pure water the closer molality and molarity come to equalling each other. This is because the molality uses mass and molarity uses volume, the ratio of these two (mass and volume) is density, and water has the density of 1 therefore the mass and volume are equal to each other. THEREFORE calculating the molarity of water is the same as calculating the molality of water.
Moles of a solute per kilogram of a solvent?
The number of moles of solute dissolved in 1 L of a solution would be the molarity. As an example, if you had 2 moles of solute in 1 liter the molarity would be 2M.
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.
Why you use molality in biology experiments?
Molality is used when temperature varies in an exothermic or endothermic reaction because it is not dependent on temperature or pressure. Molality does not depend on tempratute whereas molarity does.
Is 0.001mhcl a strong acid?
HCl is a strong acid no matter the molarity or molality.
Is molality or molarity expressed in grams of solute instead of moles of solute?
Molarity is a measure of the concentration of a solution, and therefore cannot be said to be just moles.It is in fact moles per litre (mol/L), or molars.
What terms are used to describe solutions with different amounts of solute?
Molarity or Molality
What quantity represents the ration of the number of moles of solute per kilogram of solvent?
Mol is a cocentration unit !
What is the molality of a solution that has 4 mol of KCl in 0.800 kg of water A.?
4 mol over 0.800 kg
Explain why molality is used for boiling point elevation and feezing point depression calculations and molarity is used for osmotic pressure calculations?
Molality is independent of temperature, so when you are trying to find changes in boiling and freezing points you need something that will stay constant regardless of the change in temperature. Molarity is temperature dependent and also is based on the volume of a solution, both of which are needed to calculate pressure using the ideal gas law, PV=nRT. Osmotic pressure is similar but we substitute the number of moles of the solution and the volume by using the molarity, you cannot do this with molality, since it is dependent on mass, not volume.
Molarity is to moles of solute over liters of solution as molality is to?
moles of solute over kg of solvent
