WebAnswer (1 of 7): The trick is the question “How many atoms of H per Mole of water”… take Avogrado’s # for a Mole of water, and divide by 2/3 (2 H’s and 1 O). Should end up with the same number of atoms as 2 Moles of H using the traditional method since the number of atoms is invariable. Web1. Each molecule of H2O contains 2 atoms of hydrogen (as we can see in the formula) So one mole of H2O contains 2 moles of hydrogen atoms 4.26 moles of H2O contains 2x4.26= 8.52 moles of hydrogen atoms We know that 1 mole of atoms=6.022x1023 ….

WebIn-Class Activity 5 Section 3.7 The Mole How many hydrogen atoms are in 0.5 mol of H 2 O? (N A = 6.022 × 10 23 units/mol) Section 3.8 Molar Mass What is the molar mass of CO? Section 3.9 Percent Composition What is the percent composition of CO? Section 3.10 Empirical Formulas Determine the empirical formula for C 6 H 12 O WebSep 18, 2024 · The molecular weight of water is 18.01528 g/mol. So in 2.92 grams there are 2.92/ 18.01528 = 0.1621 mol of particles. 1 mol contains 6,02214 × 10^ 23 particles by definition. So the nr of H2O molecules is 0.1621 * 6,02214 × 10^23 = 0,9761 × 10^23. Every molecule has 2 H atoms, so you have to double that. WebFeb 25, 2024 · Answer 2: Because the molecular mass of Hydrogen is 1 gram/mole, there is 1 mole of hydrogen in 1 gram of hydrogen atoms. For every mole, there are 6.02*10 23 atoms, so in 1 gram of hydrogen there are 6.02*10 23 hydrogen atoms (in scientific notation) this is equal to 602000000000000000000000 hydrogen atoms.
