Question

What is the molarity of a 1.50-liter solution containing 14 grams of HCl?

Answer 1

Molarity = moles of solute
                 ----------------------------------
                  volume of the solution
        

Moles of HCl = weight of HCl
                         ----------------------------
                          molar mass of HCl
 
                       = 14
                          ------
                          36.46
                       
                       =  0.38 moles.

Therefore molarity =  0.38
                                    --------
                                      1.5
                                 =  0.253M.

Hope this helps!!

Answer 2

Answer: The molarity of the solution is 0.2557 M.

Explanation:

Mass of the HCl contained by the solution = 14 g

Volume of the solution = 1.50 L

Molarity = $\frac{\text{Mass of the compound}}{\text{Molar mass of the compound}\times \text{Volume of the solution in L}}$

$M=\frac{14 g}{36.5 g/mol\times 1.50 L}=0.2557 M$

The molarity of the solution is 0.2557 M.
