8.1 moles of HCl is put into a beaker with enough water to make a total of 189.98 milliliters of
solution. What is the molarity of the resulting solution? (Round the answer to two decimal places
regardless of significant figures. Do not include units in the answer.)

Answer:

42.64 M

Explanation:

Step 1: Given data

  • Moles of HCl (solute): 8.1 mol
  • Volume of the solution: 189.98 mL

Step 2: Convert the volume of the solution to liters

We will use the relationship 1 L = 1,000 mL.

[tex]189.98 mL \times \frac{1L}{1,000mL} = 0.18998L[/tex]

Step 3: Calculate the molarity of the solution

The molarity is equal to the moles of solute divided by the liters of solution.

[tex]M= \frac{8.1mol}{0.18998L} = 42.64 M[/tex]
