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.
= 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.MOLARITY:The molarity of a solution can be calculated by dividing the number of moles in the substance by its volume. That is;Molarity = no. of moles ÷ volume The number of moles in 25g of HCl can be calculated as follows:moles of HCl = 25g ÷ 36.5g/molmoles of HCl = 0.685molMolarity of HCl = 0.685mol ÷ 0.150LMolarity of HCl = 4.56M
Therefore, the molarity of a solution that contains 25g of HCl in 150mL of solution is 4.56M.
