Question

if 9.4gm of KOH is dissolved in water to make a final volume of 2.0 liter,what is the molarity of solution​

Answer 1

Given mass of koh = 9.4gram

molar mass of koh = 56g/mol

Number of moles of koh in the solution

= givem mass / molar mass = 9.4g/56g/mol =0.16mol

Molality of the solution :

M = Number of moles / volume of solution

M = 0.16mol/2.0litre(net volume)

Molarity = 0.08M

Answer 2

Answer:

0.084

Explanation:

molarity is defind as amount of solute in gram divided by molar mass of solute and volume of solution.
