Q1. Molarity of Hcl
Ans. 
Molarity of HCl is a measure of concentration of hydrochloric acid in a solution.
• Molarity is defined as the number of moles of solute per liter of solution.

• To calculate molarity, divide the number of moles of solute by the volume of the solution in liters.

• For example, if you have 0.5 moles of HCl in 1 liter of solution, the molarity would be 0.5 M.
