Calculate the molarity of a solution prepared by diluting 200.0 mL of 4.0 M HCl to 500.0 mL of solution.
a. 1.1 M
b. 1.6 M
c. 2.7 M
d. 10. M
Concentration and Molarity:
When concentrations are expressed in terms of molarity, dilution plays a major role. Before and after the dilution, the moles of solute remains unchanged and therefore, the product of molarity-volume is constant.
Answer and Explanation: 1
We are given the following data:
- The initial molarity of HCl is 4.00 M.
- The initial volume of HCl is 200.0 mL.
- The final volume of HCl is 500 mL.
