To make a 2.0-mole solution, how many moles of solute must be dissolved in 0.50 liters of solution?

0.25 moles solute

0.50 moles solute

1.0 mole solute

2.0 moles solute

There are a number of ways to express concentration of a solution. This includes molarity. Molarity is expressed as the number of moles of solute per volume of the solution. The concentration of the solution is calculated as follows:

 Molarity = 2.0 mole / L solution

2.0 mole / L solution ( 0.50 Liters ) = 1 mole solute

The correct answer is the third option. One mole of solute needed to make 0.50 liters of 2M solution.
