Bohut besi calculation, yaar! Ekta simple example di sun... molarity means moles per litre of *solution*, molality is moles per kilo of *solvent*. Aru mole fraction ta just proportion. Eitu textbook-e ase, huh.
Kintu lab practical aru theory'r majot difference hoi, aami experience korisu. Thik math pura koribo lagibo, but tumar solvent volume change hoi temperature'ta – lab-e pisot scale ta namsute error dei!
Eibur murat, 10 a.m. canteen-te chemistry discuss koribo, sunlight-e chalk dust glittering – theory-ta besi clean, real life-ta besi blurry.
