Question

difference between molarity and molality​

Answer 1

Answer:

$\bold{Molarity\:( molar\: concentration )} \\ \implies \: The \: concentration \: of\: a \:substance\: in \:a\\ \:\:\:\:\:\:\:\:\:\:\:solution \:is \:usually \:expressed \\ \:\:\:\:\:\:\:\:\:\:\:in\: \:the\: unit\: called \: ' molarity'. \\ \\ \bold{Molality} \\ \implies \: molality\: is\: a\: property \:of \:a\: solution \:and\: is \\\:as \:the \:number\: of \:moles \:of \:solute\: per\: kilogram \:of\\ \:solvent. \:The \:SI \:unit \:for \:molality\: is\: mol/kg.$

Answer 2

Answer:

An important distinction between molality and molarity is the difference between a solution and a solvent. Molarity is the ratio of the moles of a solute to the total liters of a solution. Molality, on the other hand, is the ratio of the moles of a solute to the kilograms of a solvent.
