A molecule of water is made up of 2 atoms of hydrogen and 1 atom of oxygen. What percent of the atoms of a water molecule is oxygen?
1/3 = 33%
Numbers of atoms in molecule of water
1+2=3
1 atom of oxygen is:
(1/3)*100%=0.33333*100%=33.333%
Anonymous is right. It's 33.33%
Thank you both!!
To determine the percentage of oxygen atoms in a water molecule, we need to calculate the ratio of oxygen atoms to the total number of atoms in the molecule and then multiply it by 100.
In a water molecule, we have 2 atoms of hydrogen and 1 atom of oxygen. Therefore, the total number of atoms in a water molecule is 2 + 1 = 3.
To find the percentage of oxygen atoms, we divide the number of oxygen atoms by the total number of atoms and multiply by 100:
(1 oxygen atom / 3 total atoms) * 100 = approximately 33.33%
So, approximately 33.33% of the atoms in a water molecule are oxygen atoms.
