How many atoms are there in 1 mole of H2O - Toppr
Webshows the numbers of each type of element and so one mole of water (H 2 O) has two moles of hydrogen and one mole of water. That is the mole fraction of hydrogen is 2/3 (.6667) and the mole fraction oxygen is 1/3 (.3333), meaning the mole fraction for water is 67% hydrogen and 33% oxygen. WebChemistry questions and answers How many moles of hydrogen atoms are present in a sample that contains 3.64 moles of water, H2O? answer=___________mol H How many moles of H2O molecules are present in a sample that contains 5.54 moles of hydrogen atoms? answer=____________mol H2O This problem has been solved! WebMar 16, 2024 · 1) Hydrogen atoms needed to produce two H2O molecules are : • General equation of producing one molecule of H2O : H2 + 1/2O2 => H2O • For producing two molecules of H2O, we need 4 H2 and one O2 molecule • Hence equation will be, 2H2 + O2 => 2H2O •Total atoms of hydrogen required = 4. 2) Oxygen atoms needed to produce two … css fp
