Answer: The concentration of solution made by the student is 1 M.
Step-by-step explanation:
Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L.
The formula used to calculate molarity:
.....(1)
Given values:
Moles of solute = 0.5 moles
Volume of solution = 500 mL
Plugging values in equation 1:

Hence, the concentration of solution made by the student is 1 M.
