Question

What is the molarity of 40ml of NaOH if it takes 25ml of 0.5 molar HCl to neutralize it?

Answer 1

Molarity of 40 ml of NaoH is 0.3125 mL

Step-by-step explanation:

As we know

Molarity of acid * volume of acid = molarity of base * volume of base

Substituting the given values, we get

`0.5 * 25 = X* 40 \\X = (0.5*25)/(40) \\X = 0.3125`

Molarity of 40 ml of NaoH is 0.3125 mL
