35.5 moles of Lithium fluoride is dissolved in 65 L of solution. Calculate the molarity.

Hint: Molarity (M) = moles/liters

Answer :

Answer:

The molarity is 0.546 [tex]\frac{moles}{liter}[/tex]

Explanation:


In a mixture, the chemical present in the greatest amount is called a solvent, while the other components are called solutes.

Molarity is a unit of concentration based on the volume of a solution and is defined as the number of moles of solute per liter of solution. In other words, molarity is the number of moles of solute that are dissolved in a given volume.


The Molarity of a solution is then expressed as:


[tex]Molarity (M)=\frac{number of moles of solute}{dissolution volume}[/tex]

Molarity is expressed in units ([tex]\frac{moles}{liter}[/tex]).

In this case:

  • number of moles of solute: 35.5 mole
  • dissolution volume: 65 L

Replacing:

[tex]Molarity=\frac{35.5 moles}{65 L}[/tex]

Solving:

Molarity=0.546 [tex]\frac{moles}{liter}[/tex]

The molarity is 0.546 [tex]\frac{moles}{liter}[/tex]

Answer:

The molarity of Lithium fluoride is 0.5462 M

Explanation:

Molarity is the number of moles of solutes per litre of solution. Mathematically, molarity = moles / volume in litres

moles = 35.5 moles

Litre = 65 L

Molarity = 35.5 / 65

Molarity = 0.5462 M or 0.5462 mol/ L
