WebFor 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. Answer 3: Hydrogen has an atomic mass of 1.01 atomic mass units. An atomic mass unit is TINY. WebJan 30, 2024 · Notice that each water molecule can potentially form four hydrogen bonds with surrounding water molecules: two with the hydrogen atoms and two with the with the oxygen atoms. There are exactly the right numbers of δ + hydrogens and lone pairs for every one of them to be involved in hydrogen bonding.

Answer:Assuming 100\% purity, there are 6.02214086 * 10^23 atoms of oxygen present in 18g of water. Atomic weight of hydrogen is about 1, atomic weight of oxygen is almost 16. Water is H2O so it’s atomic weight is 1*2 + 16, that’s 18. how a propane tank valve works
