d
300 mL of 1.00MHCI

Answer:

  a.  800 mL of 2.00M HCI

Step-by-step explanation:

The number in front of the M is the value of the molarity, the number of moles per liter in the solution. The larger that number is, the more concentrated the solution is. In this list, the 2.00M solution is the most concentrated.
