Step 1

Solution stoichiometry involves the calculation of concentration of solutions in the given conditions of volumes, moles etc.

Solution stoichiometry is mainly based on the calculation of moles and volumes. These two values are used to calculate the molarity of solution. The relation between moles, volume and molarity is as given below; help_outlineImage TranscriptioncloseMoles of solute Molarity volume of solution in L Mass of solute ing Molar mass of solute (g/mol) Moles hence: Mass of solute in g Molarity Molar mass of solute (g/mol)xvolume of solution in L fullscreen
Step 2

Moles of HCl = 0.0084 moles

Volume of HCl = 1500 mL  =  1.5  L

Substitute the values to calculate molarity: help_outlineImage TranscriptioncloseMoles Molarity volume of solution in L 0.0084 moles Molarity 1.5 L Molarity 0.0056 M fullscreen
Step 3

HCl is a strong acid which ionized to give...
