Question

How many moles of LiF would be required to produce a 2.5 M solution with a volume of 1.5L

Answer 1

Multiply the values.

n = cv

Where

n =mol

c = concentration

v = volume

n = 2.5×1.5 = 3.75mol

Answer 2

The moles of LiF in 1.5 L solution of 2.5 M are 3.75 moles.

What is molarity?

Molarity is given as the moles of solute present in a liter of solution. It can be expressed as:

Molarity = Moles/ Volume

The moles of LiF in 2.5 M solution are:

2.5 M = Moles/ 1.5 L

Moles = 2.5 M * 1.5 L

Moles = 3.75 moles

The moles of LiF in 1.5 L solution of 2.5 M are 3.75 moles.
