1.	Problem 2.17: Calculate the molarity ofNaOH in the solution prepared by dissolvingits 4 g in enough water to form 250 mL ofthe solution.
Answer» We KNOW that $<klux>MOLES</klux> = wt \: given \: \div molecular \: wt$ moles=4/40=0.1 moles VOLUME of solution=250ml=0.25L Molarity =Moles of solute ÷ Volume of solution in litre =0.1/0.25=0.4 hope it helps

Problem 2.17: Calculate the molarity ofNaOH in the solution prepared by dissolvingits 4 g in enough water to form 250 mL ofthe solution.

Answer»

We KNOW that

$<klux>MOLES</klux> = wt \: given \: \div molecular \: wt$

moles=4/40=0.1 moles

VOLUME of solution=250ml=0.25L

Molarity =Moles of solute ÷ Volume of solution in litre

=0.1/0.25=0.4
