To convert from grams to atoms, we need 1) the molar mass, 2) The mole ratio between oxygen in water and water itself, and 3) The number of atoms in a mole. The molar mass of water is 18.02 grams/mole (H2O -> 1.01 + 1.01 + 16.00). For every one mole of H2O, there is one mole of oxygen, so that part is easy. The number of atoms in a mole is also known as Avagadro's constant. This number is 6.02x10^23. Now let's put it all together: 18g H2O x 1 mol H2O/18.02g H2O x 1 mol O/1 mol H2O x 6.02x10^23 atoms/1 mol O = 6.0x10^23 atoms (rounded to two significant digets, because the 18g had only 2 sig. figs)
In one molecule of water there are 3 atoms. One oxygen atom and two hydrogen atoms.
In a water molecule (H₂O), there are two hydrogen atoms for every one oxygen atom. This means that the number of hydrogen atoms is twice the number of oxygen atoms in water. Therefore, the number of hydrogen atoms is 2 times larger than the number of oxygen atoms.
67.5 grams of H2O
In a molecule of water (H₂O), there are two hydrogen atoms for every one oxygen atom, making the number of hydrogen atoms twice as large as the number of oxygen atoms. This ratio is the same for monosaccharides, such as glucose (C₆H₁₂O₆), where there are also twice as many hydrogen atoms as oxygen atoms. Thus, both water and monosaccharides have a 2:1 ratio of hydrogen to oxygen atoms.
6.6x1022 per gram of water
3,45 grams of H2O contain 1,154.10e23 oxygen atoms.
There are 7.24 x 10^23 atoms of oxygen in 13 grams of water. This calculation is based on the molar mass of water (18.015 g/mol) and the fact that each water molecule contains two hydrogen atoms and one oxygen atom.
1 third because water is composed by 2 oxygen atoms and 1 of hidrogen, so 207÷3=69 grams.
0.87 grams water (1 mole H2O/18.016 grams)(1 mole O/1 mole H2O)(6.022 X 1023/1 mole O) = 2.9 X 1022 atoms of oxygen --------------------------------------
One mole of oxygen has a mass of 16 grams and contains 6.022 x 10^23 oxygen atoms. Therefore, 16 grams of oxygen will also contain 6.022 x 10^23 oxygen atoms.
There are 424 grams of oxygen in 477 grams of water. 8 times 53 equals 424.
It depends on how much water you have!
The molar mass of water(H2O)=18((1*2)+16)The no. of moles(n) of water in 18 g of water=mass/molar mass=18 g/ 18 g mol-1 =1 molThe no. of molecules of water in 18 of water=n*Avogadro no. =1 mol*6.022*1023 mol-1 =6.022*1023The no. of atoms of oxygen in one mole of water=1 molThe no. of atoms of oxygen in 6.022*1023mol of water= 6.022*1023
There are 8 oxygen atoms in 4 water molecules.
No, the chemical formula for water is H2O. This means that for every oxygen atom in the compound, there are two hydrogen atoms. Thus, the number of hydrogen atoms in water is double the number of oxygen atoms.
0, but there is 1 atom of Oxygen in water.
3 oxygen atoms in three molecules of water.- There are 3 total atoms in water, which is H2O. There are 2 hydrogen atoms (H), and 1 oxygen atom (O).
