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 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.
What is the molality of a solution made by dissolving 3 mol of NaOH in 6 kg of water?
Molality is defined as moles of solute per kg of solvent. Thus, 3 moles/6 kg = 0.5 moles/kg = 0.5 m
What would you needto do to calculate the molality to 10 molecules of NaCl in 200 molecules of water?
Molality of a solution is defined as the number of gram moles, for molecular compounds, or gram formula unit masses, for ionic compounds, mixed with each kilogram of solvent. Sodium chloride is the solute in the question, and water is the solvent. Avogadro's Number is defined as the number of formula units required to constitute one gram formula unit and has the value of about 6.022 X 1023. Therefore, 10 formula units of NaCl constitutes 10/(6.022 X 1023) or about 1.6606 X 10-23 gram formula unit. The gram molecular mass of water is 18.0518. Therefore, 200 molecules of water contains (200)(18.0518)/(6.022 X 1023) or about 599.5 X 10-23 grams or 0.5995 X 10-23) kilograms. Therefore, the molality of the given mixture is 1.6606/0.59995* or about 2.768. ________ *The number 10-23 appears in both numerator and denominator, and therefore need not be included in this fraction.

What formula is used to calculate delta T?
(delta)T=Kf (freezing point depression contstant_ x m (molality) x i
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.
What is molality?
Concentration
How are concentrations in solutions quantified?
through molarity,molality, normality. through molarity,molality, normality.
What is the molality of a solution made by dissolving 2 moles of NaOH in 10 kg?
The molality is 0,2.
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.
What is the molality solution that has 3 mol of glucose in 6 kg if water?
This molality is 90,08 g/kg.
What is the molality of ethanol in a solution made by dissolving 14.6 g in 53.6 g of water?
The molality of ethanol will be 5,91.
What is the molality of a solution made by dissolving 2 moles of NaOH in 6 kg of water?
0.33 mol/kg (apex)
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.
