An atom is the smallest particle of an element, like oxygen or hydrogen. Atoms join together to form molecules. A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom. That's why water is sometimes referred to as H 2 O. A single drop of water contains billions of water molecules. the past tense of have
How to Find the Number of Atoms in H2O2 (Hydrogen peroxide)
WebJan 9, 2024 · 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 many molecules of H2O are there in 18g of water? WebMar 8, 2024 · The formula H 2 O indicates that each molecule of this substance contains one oxygen and two hydrogen atoms. Therefore, if we ask how much hydrogen is required to make a given quantity of water, the answer is two hydrogen atoms for each oxygen atom or two hydrogen atoms per molecule.
