Sagot :
The molarity is a concentration unit which defined as the number of moles of solute divided by the number of liters of solution. So the molarity of the solution is 3/2=1.5 mol/L.
Given that
Volume of solution = 2.0 L
Number of mole of solute = 3.0 mole
Therefore molarity = number of moles / volume in L
= 3.0 Mole /2.0 L
= 1.5 mole / L
= 1.5 M
Molarity:
The number of moles of solute per liter of solution is known as molarity of the solution. It symbolized by M. Molarity of any solution is a ratio of moles of solutes per liter of solution. It expressed by the following formula:
molarity = number of moles / volume in L
