If water sample are taken from sea, rivers or lake, they will be found to contain hydrogen and oxyge — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

The law of definite proportion states that a given chemical compound always contains its component elements in a fixed ratio (by mass) and this ratio does not change if we change the source or method of preparation. In all the water samples, taken from the sea, rivers, lakes or snow-capped mountains, the hydrogen and oxygen ratio is constant, clearly demonstrating the law of definite proportions.
