Sir you described percentage concentration but ncert has a concept of mass percentage(w/w) and volume percentage (V/V) and also parts per million which are totally different. Please explain these concepts also.
henry law kya hai aur henry law kis chiz par depend karta hai woh topic thora xplain kar dijiye?????? ncert maein hai
sir please tell these questions
1-In a solvent 50% of benzoic acid dimerises while rest ionises,determine molar mass of acid which is obsereved and also its vant hoff factor?
2-vapour pressure of solvent decreases by 1% on adding a non volatile solute Na2SO4.If it dissociates up to 25% then determine mole fraction of solute, if solvent is 5 mole
Sir in the 3rd numerical how molality is same for boiling and freezing ?
