Question

which among the two is more concentrated (1)2M KNO3 or (2) 2m KNO3​

Answer 1

Explanation:

1) 2M KNO3

Hope this helps

Answer 2

Answer:

I think 2m ( molality ) of KNO₃ is more conc.

 because it is number of moles of solute / mass in Kg of solvent

     where molarity is number of moles of solute / volume in L of total solution

from here we can see that volume of total sol. is greater than mass in Kg . so , (2) 2m KNO3 is more concentrated
