What is the diffidence between morality and MOLALITY?
Morality(M)= moles of solute divided by grams of solution Molality(m)= moles of solute divided by kilograms of solvent to convert from grams to kilograms you move the decimal 3 units to the left.
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.
Formula for molality?
== Molality== (1000xMolarity)/((1000xdensity of solution)- (MolarityxMolecular weight of Solute)) ==
What concentration units is measured in mole of solute per kilogram of solvent?
This the molality (this term is now obsolete).
What concentration units is measured in moles of solute per kilogram of solvent?
This the molality (this term is now obsolete).
What is the diffidence between morality and MOLALITY?
Morality(M)= moles of solute divided by grams of solution Molality(m)= moles of solute divided by kilograms of solvent to convert from grams to kilograms you move the decimal 3 units to the left.
What is the molality of a solution that has 70g of NaCl dissolved in 300g of water?
Molality(m)= moles of solute divided by kilograms(kg) of solvent you need to find the moles of NaCl by using a conversion factor 70g NaCl = 1mol divided by 58.44g NaCl =1.20mol then you need to convert 300g of water which is the solvent to kilograms by moving the decimal over 3 units to the left which makes .300 kg of solvent Molality= 1.20mol divided by .300kg Molality=4.00
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 16.1 g of Cl2 dissolved in a 5000 g water?
Molality(m)= moles of solute divided by kilograms of solvent you need to find the moles of solute of chloride first by using a conversion factor. 16.1g of Cl2 = 1mole divided by 70.90g of Cl = 0.23mol then you need to convert 5000g of water which is the solvent to kilograms which to convert it you move the decimal 3 units to the left so it is 5.000kg then you put it into the equation so it would be Molality(m)= 0.23mol divided by 5.000kg of solvent Molality= 0.05
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.
