what is the molarity of NaOH solution if 250 ML of it contains 1 mg of NaOH
Hello Rahul,
To calculate the molarity of the NaOH solution, follow these steps:
-
Given Data :
-
Mass of NaOH = 1 mg
-
Volume of NaOH solution = 250 mL
-
-
Convert Mass to Grams : Since 1 mg = 0.001 g, the mass of NaOH is 0.001 g.
-
Convert Volume to Liters : Volume is given in mL, so convert it to liters: 250 mL = 0.250 L.
-
Molar Mass of NaOH : The molar mass of NaOH (Na = 23, O = 16, H = 1) is 40 g/mol.
-
Calculate Moles of NaOH : Moles of NaOH = Mass of NaOH (in grams) / Molar mass of NaOH
Calculate Molarity
: Molarity (M) = Moles of solute / Volume of solution (in liters)
So, the molarity of the NaOH solution is
0.0001 M
. This indicates a very dilute solution of NaOH.
