Question

Concentrated HCl has a concentration of 12.0M HCl. What volume in mL of this solution would one need to get 0.425 mol of HCl?

Answer 1

0.035L

35.4mL

Explanation:

Given parameters:

Concentration of HCl = 12M

 Number of moles = 0.425mol

Unknown:

volume of solution = ?

 convert from L to mL = ?

Solution:

 Molarity is the amount of solute in a volume of solvent

   Molarity = $\frac{number of moles }{Volume}$

   

since the volume is the unknown, we make the subject of formula;

    Volume = $\frac{number of moles }{molarity}$

     Volume = $\frac{0.425}{12}$ = 0.035L

Converting to mL gives:

               1L = 1000mL

             0.035L = (0.035 x 1000)mL , 35.4mL
