Web8 apr. 2024 · In 1 mole of water → 6.023 × 10 23 molecules are present So, in 1 18 moles of water → 6.023 × 10 23 × 1 18 molecules = 0.3346 × 10 23 molecules = 3.346 × 10 22 molecules So, we can conclude that in 1 ml of water the number of molecules present is 3.346 × 10 22. Hence the correct option is: (C) 3.346 × 10 22 http://scienceline.ucsb.edu/getkey.php?key=6906 Web19 aug. 2024 · Since one mole is defined as 6.022 x 10^23, and there are two hydrogen per molecule, that would mean that there are exactly 12.044 x 10^23 molecules of hydrogen in one mole of water. Double that for 2 moles, and there are 24.088 x 10^23 hydrogen atoms in one mole of water. How many water molecules are in a glass of water? how are stones used in the bible
