Molarity is the no of moles of solute per dm3 solution, the temperature change changes the volume so molarity becomes effected.
Yes, molarity changes with the change in temperature.
Molarity 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.
Molarity of a solution depends upon volume of solution, the change in temperature changes the volume so molarity changes.
Mol is a cocentration unit !
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).
Molality is moles solute per kilograms of solvent, so 2/10=0.2m.
The molality is 5,54.
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
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.
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.
its temperature dependent
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.
Molality of a solution remains constant as mass of a solution independent of temperature.
volume or temperature
Mol is a cocentration unit !
atmosphere
A series of light-dependent reactions that are temperature independent, and a series of temperature-dependent reactions that are light independent.
The Temperature is the Independent Variable (50 degrees, 100 Degrees etc.) Whatever happens as a result of the temperature change is the dependent variable.
Molality is the number of moles of a solute divided by the weight of the solvent in kilograms.
The molality is 0,07.
