What is the molarity of a solution that contains 25 g of hcl in 150 ml of solution? (the molar mass of hcl is 36.46 g/mol.)

Explanation:

Molarity is defined as number of moles of solute in liter of solution.

Whereas number of moles is equal to mass of given substance divided bu its molar mass.

Since molar mass of HCl is 36.46 g/mol. Therefore, calculate the number of moles of HCl as follows.

                                             =

                                             = 0.686 mol

Hence, molarity of solution will be as follows.

              Molarity =

                            =

                            = 4.573 mol/L

Thus, we can conclude that molarity of  a solution that contains 25 g of HCl in 150 mL of solution is 4.573 mol/L.

The molarity of a solution that contains 25g of HCl in 150mL of solution is 4.56M.

Therefore, the molarity of a solution that contains 25g of HCl in 150mL of solution is 4.56M.
