Explanation:
A closed system is completely closed to the outside environment. Every interaction is transmitted inside that closed system.
Molarity = Moles/Liters. First, convert all ml to Liters by moving the decimal 3 places to the left and then calculate:
.001 L HCl x 6M/L HCl /.5 Liters of solution=0.012 Moles per Liter aka molarity
