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

To make 500mL of 3N NaOH solution, you need to dissolve 15g of NaOH pellets in enough water to make 500mL of solution. Calculate the amount of NaOH needed by using the formula: (g = (N \times M \times V) / 1000), where (N = normality (3N)), (M = molar mass of NaOH (40 g/mol)), and (V = volume in liters (0.5 L)).

Answer 3

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.
