00 kg sample of water (H₂O) contains 0.11 kg of hydrogen (H) and 0.89 kg of oxygen (O). According to the law of constant composition, how much hydrogen and oxygen would a 1.5 kg sample of water contain?

Question

Quizplus · Accepted Answer

The law of constant composition states that a chemical compound always contains its component elements in fixed ratio by mass and does not depend on its source and method of preparation. Therefore, to find the amount of hydrogen and oxygen in a 1.5 kg sample of water, we scale the amounts in the original 1.0 kg sample by 1.5. This gives 0.11 kg * 1.5 = 0.165 kg of hydrogen (rounded to 0.17 kg) and 0.89 kg * 1.5 = 1.335 kg of oxygen (rounded to 1.34 kg).
