How do you make 500ml of 3N NaOH?

Answer 1

Since HCl is a monoprotic acid, its normality is the same as its molarity. A 4 N solution of HCl is a 4 M solution of HCl as well. If you want to make a liter of a 4 N solution of HCl, you need to dilute a certain volume of a standard solution you already have to one liter (1,000 mL) of the 4 M solution. You could use a standard concentrated solution of HCl that is usually 12 M using the following equation:

(V1)(M1) = (V2)(M2)

V1 = ?

M1 = 12 M

V2 = 1,000 mL

M2 = 4 M

V1 = [(V2)(M2)] / ((M1)

V1 = [(1,000 mL)(4 M)] / (12 M)

V1 = 83 mL

According to the above calculations, to make 1,000 mL (1 L) of a 4 M solution of HCl, you would need to dilute with water 83 mL of 12 M solution of HCl to 1,000 mL (1 L) volume. As stated before, a 4 M solution is also a 4 N solution of HCl.

Answer 2

1N = 40.0g in 1000mL (1M or 1mol/L)

3N = 120.0g in 1000mL (3M or 3mol/L).

Therefore 3N (3M) in 500mL = 60g NaOH.

Answer 3

Take 28.21 ml Hcl make up to 1000 ml Dis.Water its 3N HCl

Answer 4

25.5ml hcl in 100ml of water
