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 atoms of oxygen are in each water molecule?
One atom of oxygen bonds with two atoms of hydrogen Edd
How many oxygen atoms are present in a water sample containing 4.5 x 1023 hydrogen atoms?
You must mean; how many grams of O ( one atom oxygen ) 1.23 X 10^24 molecules H2O (1 mole H2O/6.022 X 10^23)(1 mole O/1 mole H2O)(16 grams/1 mole O) = 32.7 grams of oxygen
How many atoms of oxygen are there in18g of water?
Avogadro's number
How many kg of water there is in a mol?
Water has two hydrogen atoms, and one oxygen atom. Look up their atomic weights, add them all up, and you will get the number of grams per mol.
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?
13 grams water (1 mole H2O/18.016 grams)(1 mole O/1 mole H2O)(6.022 X 1023/1 mole O) = 4.3 X 1023 atoms of oxygen ======================
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 grams of oxygen are contained in 18g of water?
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 in 3.120 grams of oxygen gas?
3.120 grams oxygen gas (1 mole O2/32 grams)(6.022 X 1023/1 mole O2) = 5.871 X 1022 atoms of oxygen gas ------------------------------------------------
How many oxygen atoms and hydrogen atoms does water have?
It depends on how much water you have!
