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.

there are two significant figures.
