Calculate the molarity of a NaOH solution that is prepared by diluting 100mL of 0.20M NaOH with 150mL of H2O.
lianna [129]

Molarity of solution = 0.08 M

<h3>Further explanation  </h3>

Molarity shows the number of moles of solute in every 1 liter of solution or mmol in each ml of solution  

\tt M=\dfrac{n}{V}  

Where  

M = Molarity  

n = number of moles of solute  

V = Volume of solution  

  • mol of NaOH

\tt mol=0.2~M\times 100~ml=20~mlmol=0.02~mol

  • molarity

Volume of solution = 100 ml + 150 ml = 250 ml

\tt M=\dfrac{0.02~mol}{0.250~L}=0.08
