PLEASE HELP QUICKLY!! If it takes 35 mL of 0.05 M HCl to neutralize 315 mL of NaOH solution, what is the concentration of the NaOH solution?

Molarity is the concentration of a solution expressed as the number of moles of solute per litre of solution.

Explanation:

To get the molarity, you divide the moles of solute by the litres of solution.

Molarity

=

moles of solute

litres of solution

For example, a 0.25 mol/L NaOH solution contains 0.25 mol of sodium hydroxide in every litre of solution.

To calculate the molarity of a solution, you need to know the number of moles of solute and the total volume of the solution.

To calculate molarity:

Calculate the number of moles of solute present.

Calculate the number of litres of solution present.

Divide the number of moles of solute by the number of litres of solution.
