Molarity is the no of moles of solute per dm3 solution, the temperature change changes the volume so molarity becomes effected.

∙ 11y agoYes, molarity changes with the change in temperature.

∙ 13y agoMolarity is moles/liters. As temperature is increased, the volume of the solution will increase, making the denominator greater, while keeping the numerator constant, thus decreasing M.

What quantity represents the ration of the number of moles of solute per kilogram of solvent?
Mol is a cocentration unit !
How is temperature affected by freezing point?
I think you are asking about the following formula: ΔT = Kf m i where ΔT is the change in freezing point, Kf is a constant dependent on the identity of the substance, m is the molality (the kilograms of solute per liters of solvent), and i is the Van't Hoff number (the number of particles that each formula unit of the solute breaks up into).
What is the molality of a substance made by dissolving 2 moles of NaOH in 10 kg of water?
Molality is moles solute per kilograms of solvent, so 2/10=0.2m.
What are the molality and mole fraction of solute in a 25.5 percent by mass aqueous solution of formic acid (HCOOH)?
The molality is 5,54.
When a certain amount of calcium chloride (CaCl2) was dissolved 100.g of water the boiling point rose from 100.0C to 104.4C calculate the molality of this solution.?
Delta T = imKI = van't Hoff factor = 3 for CaCl2 m = molality = moles solute/kg solvent = ? K = boiling point constant for water = 0.512 Delta T = change in temperature = 4.4 deg C Plug in the values and solve for m
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.
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.
Joule Thomson effect is temperature dependent or not?
its temperature dependent
What is one advantage of percentage over molarity as a measure of solute concentration?
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.
Why molarity of a solution remains constant?
Molality of a solution remains constant as mass of a solution independent of temperature.
What is the dependent variable in a temperature test?
volume or temperature
What quantity represents the ration of the number of moles of solute per kilogram of solvent?
Mol is a cocentration unit !
The temperature of a place is dependent on what?
atmosphere
What are the two stage of photosyntesis?
A series of light-dependent reactions that are temperature independent, and a series of temperature-dependent reactions that are light independent.
What is the dependent variable in a temperature experiment?
The Temperature is the Independent Variable (50 degrees, 100 Degrees etc.) Whatever happens as a result of the temperature change is the dependent variable.
What is the molality of a substance?
Molality is the number of moles of a solute divided by the weight of the solvent in kilograms.
What is the molality of a solution containing 10.0g of Na2SO4 dissolved in 1000.0g of water?
The molality is 0,07.
