What is the number of hydrogen atoms in a 18.016 gram sample of water? A) 2.000 B) 6.022 * 10²³ C) 18.02 D) 1.204 * 10²⁴

Question

Quizplus · Accepted Answer

18.016 grams of water is equivalent to 1 mole of water (since the molar mass of water is approximately 18.016 g/mol). Each molecule of water (H2O) contains 2 hydrogen atoms. Therefore, 1 mole of water contains 2 moles of hydrogen atoms, which is 2 * 6.022 * 10^23 = 1.204 * 10^24 hydrogen atoms.
