Question

an aqueous solution has 109.2g koh/l solution the solution density is 1.09 g/ml your task is to use 100.0 ml of this solution to prepare 0.250m​

Answer 1

Answer:

0.25 m is answer so mark me as brainlist

Answer 2

Molarity= GMW of KOHWeight of KOH×Vol(ml)1000             

[GMW of KOH= Atomic weight of K+ atomic weight of O+ atomic weight of H=10+16+1=27]

⇒0.1=27Weight of KOH×1001000                        

Weight of KOH=102.7

Weight of KOH=0.27 g
