Question

Describe how to prepare 1.00 L of 0.646 M HCl solution, starting with a 2.00 M HCl solution.

 

 

 

Strategy

  • Because the concentration of the final solution is less than that of the original one, this is a dilution process.
    Keep in mind that in dilution, the concentration of the solution decreases but the number of moles of the solute remains the same. 
  • Solve for the volume in (mL) of 2.00 M HCl needed to prepare 1.00 L of a 0.646 M HCl solution.

Note: Answers must be numeric, not alphanumeric—42, not forty-two.
