At what temperature did the kcl begin to crystallize from the solution of 4.0 g kcl in 10 ml h2o? select the closest answer.

Respuesta :

The  molarity of the Solution is 6.9M . Molarity is inversly proportional to the temperature.

What is Molarity?

Molarity is amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution. Molarity is known as the molar concentration of a solution.

Molarity = no. Of moles / Volume  

The S I unit of Molarity is M .

Weight of KCl is 4

molar mass of the KCl is 58g/ mol .

Volume of the solution is 10 ml

 .           → 10/ 1000 L

no of moles =4/58

Molarity  = 4×1000/ 58×10

Molarity =6.9 M

Molarity is inversly proportional to the temperature, so when Molarity increase temperature decrease or vice versa .
