4 moles of oxygen atoms (being present in 4 moles of H2O) and, so: 4 moles of oxygen atoms is 4*6.02*1023 = 24.1*1023 molecules ATOMS of oxygen
2 Hydrogen atoms and 1 Oxygen atom= water molecule
The molecular formula of water is H2O, showing that each molecule of water contains one oxygen atom. Therefore, 0.5 moles of water will contain 0.5 moles of oxygen atoms.
5 moles H2O (1 mole O/1 mole H2O)(6.022 X 1023/1 mole O)(1 mole O atoms/6.022 X 1023)= 5 moles oxygen atoms=================( as you see this is a formal set up that you do not need to use fully as Avogadro's number is over itself as a form of one )5 moles H2O (2 moles H/1 mole H2O)6.022 X 1023/1 mole H)(1 mole H atoms/6.022 X 1023)= 10 moles hydrogen atoms====================
Well if one mole of water = 2 moles of hydrogen and 1 mole of oxygen, than 2moles of water = 4 moles of hydrogen and 2moles of oxygen.
3,45 grams of H2O contain 1,154.10e23 oxygen atoms.
In excess quantity of hydrogen (H2) 5.0 moles water can be formed maximally from 2.5 mole oxygen,because 2.5 x 2 (atoms O per mole oxygen, O2) = 5.0 x 1 (atoms O per mole water, H2O), thus balancing this reaction for oxygen atoms (5 on both sides).
divide this number by avagadros number to get moles. (5.16x1024)/(6.02x1023)=8.57mol of H2O as there are 3 atoms in each molecule there are 3x8.57=25.7 moles of atoms.
This is one to one. 0.50 moles H2O (1 mole O/1 mole H2O) = 0.50 mole oxygen -------------------------
There is one oxygen atom and two hydrogen atoms.
4 moles also 2 moles of oxygen will be consumed
The answer is: 5 moles oxygen and 4 moles H2O.The reaction is:C3H8 + 5 O2 = 3 CO2 + 4 H2O
You probably mean how many atoms are in H2O. A single molecule of H2O contains 2 atoms of Hydrogen and 1 atom of Oxygen.
602,000,000,000,000,000,000,000 (6.02 X 10^23) Oxygen atoms.
A molecule of water H2O contains 3 atoms, two of Hydrogen and one of Oxygen.
NONE! H2O is Hydrogen and 2 parts Oxygen.
2.60 moles H2O (2 moles H/1 mole H2O)(6.022 X 10^23/1 mole H) = 3.13 X 10^24 atoms of hydrogen
2 moles of hydrogen, 1 mole of oxygen
There are 2.
3. Two hydrogen atoms, one oxygen atom.
There is 1 O atom in 1 H2O molecule thus there are 12 O atoms in 12 H2O molecules.
There are two oxygen atoms in a carbon dioxide molecule and one oxygen atom in a water molecule.
Two moles of water are produced.
