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)

How many atoms are there in a molecule os water?
In one molecule of water there are 3 atoms. One oxygen atom and two hydrogen atoms.
How many times larger is the number of hydrogen atoms than oxygen atoms in water?
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.
How many times larger is the number of hydrogen atoms than oxygen atoms in a molecule of water Is the number the same for monosaccharides and for water?
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.
How many grams of water are produced from 67g of oxygen?
67.5 grams of H2O
How many atoms of hydrogen are in 5 grams of water?
6.6x1022 per gram of water
How many oxygen atoms are there in 3.45 grams of H2O?
3,45 grams of H2O contain 1,154.10e23 oxygen atoms.
How many atoms of oxygen are there in 13 grams of water?
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.
How many grams of hydrogen are there in 207 grams of water?
1 third because water is composed by 2 oxygen atoms and 1 of hidrogen, so 207÷3=69 grams.
How many oxygen atoms are in 0.87 g of water?
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 --------------------------------------
How many atoms are present in 16g og 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.
How many grams of oxygen are in 477 grams of water?
There are 424 grams of oxygen in 477 grams of water. 8 times 53 equals 424.
How many oxygen atoms and hydrogen atoms does water have?
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
How many atoms of oxygen are there in all 4 moelcules of water?
There are 8 oxygen atoms in 4 water molecules.
Dose water contain half as many hydrogen atoms as oxygen atoms?
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.
How many atoms are in water of oxygen?
0, but there is 1 atom of Oxygen in water.
How many oxygen atoms are in molecules of 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).
