Chemical Stoichiometry
« on: November 01, 2009, 06:55:25 AM »
A 25.0 gram sample of KOH is placed in a 125 mL volumetric flask. The flask is then filled with water to the mark on the neck. What is the molarity of the resulting solution?

Hi Vinay
sorry I missed your question
not to worry it is a simple question
calculate number of moles of KOH
moles = mass / molar mass

molarity = no of moles / vol in L
