Mohshreen said: (May 9, 2011)  
Just I guess this answer motality but how this answer was right I don't know.

Molality is ratio of no of moles present in 1kg of solvent.

Suhani said: (Jun 12, 2011)  
Molality means the ratio of no. of present in 1kg of solvent.

Arul Kiliyur Upt said: (Jun 29, 2011)  
solute eq.wt present in1litre(solvent)=1normal(N )
solute m.w present in 1Kg(solvent) =1molal(m)
solute m.w present in 1litre(solvent)=1molar(M )

Satish said: (Jul 3, 2011)  
The difference between molarity and molality is solvent in molality in kg rather in molarity litres.

Isanika Mitra said: (Jul 16, 2011)  
Molality mean the ratio of no of present in 1kg solvent

Chandana said: (Oct 18, 2011)  
The formula of molality is
malality=no.of moles of solute/molecular wt in litres*1000/100

G.Mohan said: (Apr 13, 2012)  
The no. Of moles of solute is present in the 1 kg of solvent is called the molality.

Blessing Anne said: (May 29, 2012)  
Molality is the ratio of the no of moles of a solute to the solvent in Kg.

Papati Melubo said: (Aug 30, 2012)  
Molality is the amount of substance of a solute present per unit volume of solvent;the volume measured is that of solvent, Not the solution.

Nishit Shah said: (Jan 30, 2013)  
Molality is the ratio of the no.of moles of a solute to the solvent in kg.

Molality Is Ratio Of No Of Moles Present In 1kg Of Solvent.

Thankgod Peter said: (Apr 5, 2013)  
Molality is the number of moles of solute per kilogram of solvent.

Rajesh Biradar said: (Jul 20, 2013)  
Number of solutes present in one lit of solvent.

Sandipmane said: (Sep 6, 2013)  
I think better answer is, Molality is defined as the ratio of on of 1gram of solute in 1kg of solvent.

Ible Hasan said: (Dec 24, 2013)  
The number of moles of solute present in 1 kg of a solvent is called its molality.

The number of moles of solute present in 1 litre of a solution is called its molarity.

K.K.Kannan said: (Jan 26, 2014)  
Molality is 1g solute dissolved in 1 kg of solvent.

K.Prasanthi said: (Apr 17, 2014)  
The relation between molarity and molality 1000m/1000d-m*GMW.

Units of molality is molal.

Nagaraju Rajana said: (Apr 19, 2014)  
Molality is accurate concentration because here we are considering weight i.e. kg.

Harry said: (Oct 1, 2014)  
Molarity defined for solid i.e. solute, where as molality is defined for liquid i.e.Solution.

Nelly Franreet Akinyi said: (Nov 20, 2014)  
Its molarity not molality because this two words are confusing reason being that in chemistry under this chapter theres nothing like molality.

Rugharam Prajapat said: (Jul 11, 2015)  
In morality number of mole present in kg solution but in morality no of mole present in one kg of solvent.

Jjuuko Andrew said: (Jul 18, 2015)  
Nice explanations.

Antony Gida said: (Aug 17, 2015)  
Is molarity not molality, molarity refers to the concentration of moles per liter or mols/gram.

Ashok said: (Aug 17, 2015)  
Neon has the highest electronegativity of all elements, followed by fluorine, helium, and oxygen.

Saisree said: (Oct 8, 2015)  
Number of moles of solute present in 1 kg or 1000 gm is molality.

Rick said: (Dec 16, 2015)  
I'm trying to review for mid terms and I still can't understand how to do moles. Even in the comments.

Aaliya Khan said: (Dec 29, 2015)  
Molality is the amount of solute in 1 kg solvent.

Devadharshini. said: (Mar 29, 2016)  
It is Molarity. It is a unit of the concentration measuring the number of moles of a solute per liter of solution.

Gopi Chand said: (Apr 29, 2016)  
The number of moles of solute presents 1 kg or 1000 gm of solvent.

Mulisa said: (Jun 18, 2016)  
It is true that the number of moles of solute in 1 kg of solvent.

Molality means a number of moles of solute present in one kg of solvent.

Shaheen Mundodan said: (Jun 23, 2016)  
Molality means a number of moles of solute present in one kg of solvent.

Awotona-Abiodun said: (Jun 24, 2016)  
It's molarity, not molality.

Dileep said: (Jul 12, 2016)  
It is Molality of solvent in 1 kg.

Gabrison Munene said: (Aug 16, 2016)  
It is molarity as it is the concentration of moles per litre.

Pooran Lal Kashyap said: (Dec 1, 2016)  
Molarity is the number of solute present in one liter solvent.

Akash Syal said: (Jan 4, 2017)  
Molality is a no of moles of solute to a solvent in 1kg.

Sibu said: (Jan 20, 2017)  
Molality is defined as the 1gm.mol of solute dissolved in 1lt.

Haswanth said: (Feb 10, 2017)  
Molality is defined as a no of solute to a solvent in 1kg.

Alfred said: (Mar 22, 2017)  
Molality is the amount of solute in 1kg solvent.

Anamika Adwiteeya said: (Jul 6, 2017)  
Molarity is the correct answer because the formula says,

Molarity =moles of solute/kg of solvent.

Suresh R N said: (Jul 21, 2017)  
Solvent measured in litre is molarity.

Solvent measured in kg is molality.

Saw Yu Nandar said: (Aug 9, 2017)  
What is the difference between molarity and molality?

Shehu Muhammad Nigeria said: (Aug 25, 2017)  
The answer is molarity.

Ashley Kufakunesu said: (Aug 30, 2017)  
Thank you for the wonderful explanation.

Dhriti said: (Sep 7, 2017)  
What is the difference between molarity and normality?

Dhriti said: (Sep 7, 2017)  
Actually, Molarity(M) is defined as the no of moles of solute per 1 lit solvent and the Molality(m) is defined as the no of moles of solute per 1 kg solvent.

Raj Yadav said: (Nov 5, 2017)  
Molarity Means No of moles in a solute particle per 1 liter solvent is called a Molarity.

Elizabeth Okon said: (Jun 2, 2018)  
More explanation on molarity and molality.

Raju said: (Dec 8, 2018)  
Molality = number Of moles solute 1kg of solvent.
