As per the modified Periodic Table, the fourth element after oxygen considering their atomic weights is Ca and thus if the atomic weight of oxygen is considered to be as 16, therefore the atomic weight of Ca is 20

How would we determine the molecular weight for a molecule water h2o?

To determine the molecular weight of a molecule like water (H2O), you would add up the atomic weights of all the atoms in the molecule. For water, you would add the atomic weight of two hydrogen atoms and one oxygen atom, which gives you a molecular weight of approximately 18.015 atomic mass units (amu).


The average relative mass of an ozone molecule is 48.0 you. An ozone molecule contains only oxygen atoms. What does this molecular weight indicate about the formula of the ozone molecule?

The molecular weight of ozone indicates that an ozone molecule consists of three oxygen atoms. This is because the relative atomic mass of oxygen is approximately 16 u, and three oxygen atoms (16 + 16 + 16 = 48 u) combine to form an ozone molecule with a molecular weight of 48.0 u.


Effective atomic weight of water?

Atomic weights refer to ATOMS. Water is a MOLECULE made up of 3 atoms, it therefore does not have an atomic weight, it has a MOLECULAR weight.You calculate the molecular weight by adding up the atomic weight of all the atoms in the molecule.Waster is made up from 1 atom of Oxygen (atomic weight 16) and 2 atoms of Hydrogen (atomic weight 1)16+1+1 = 18The molecular weight of water is therefore 18.-------------------------------------------------------------------------------------The atomic mass of H is 1.008, and the atomic mass of O is 16.So 1.008*2+16=18.016


What is the average molecular weight of the compound in question?

The average molecular weight of the compound is the sum of the atomic weights of all the atoms in the molecule, divided by the number of atoms.


What is the molecular weight of the compound in question?

The molecular weight of a compound is the sum of the atomic weights of all the atoms in a molecule. It is expressed in atomic mass units (amu) or grams per mole (g/mol).

What is the sum of the atomic masses in a molecule?

The sum of the atomic masses in a molecule is called the molecular weight or molecular mass. It is calculated by adding the atomic masses of all the atoms in the molecule. This value is usually expressed in atomic mass units (amu) or grams per mole (g/mol).

What is the unit of molecular wt?

The unit for molecular weight is typically in atomic mass units (u) or daltons (Da). It represents the sum of the atomic weights of all the atoms in a molecule.


What is a molecular weight?

The sum of the atomic weights of all atoms making up a molecule. Actually, what is meant by molecular weight is molecular mass. The use of this expression is historical, however, and will be maintained. The atomic weight is the mass, in atomic mass units, of an atom. It is approximately equal to the total number of nucleons, protons and neutrons composing the nucleus. Since 1961 the official definition of the atomic mass unit (http://www.answers.com/topic/amu) has been that it is 1/12 the mass of the carbon-12 http://www.answers.com/topic/isotope, which is assigned the value 12.000 exactly.
