What is the element that makes up most of the mass of a body?
oxygen
Which element has the lowest mass on the periodic table?
The atom that has the lowest mass is hydrogen. So assuming the same numbers of atoms in each element, hydrogen would be the element with the lowest mass.
What the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
How is the molar mass of an element determined?
the Atomic Mass in g/ml is the molar mass of the element
What is the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass

Facts about the element oxygen?
is the element with atomic number 8 and represented by the symbol O.Because it comprises most of the mass in water, oxygen comprises most of the mass of living organisms (for example, about two-thirds of the human body's mass)Oxygen is a member of the chalcoqen groupof the periodic table.
What makes an element more massive?
The more protons and neutrons that are in the element and isotope electrons are negligible in terms of mass.
