You add together the atomic weights of all the atoms (as given by its chemical formula) in the molecule
The molecular weight of water is 18 lb/lbmol.
One molecule of water has a total molecular weight of approximately 18 daltons. This weight is calculated by adding the atomic weights of two hydrogen atoms (each 1 dalton) and one oxygen atom (approximately 16 daltons).
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
The molecular formula of water is H2O. This means that each water molecule contains two hydrogen atoms and one oxygen atom. The criss cross method is typically used for ionic compounds to determine the ratio of ions in the compound.
Borax is Na2B4O7·10H2O with a molecular weight of 318.37 g/mol. There are ten water molecules with net molecular weight of 180 g/mol. So the percentage of water = (180 * 100 / 318.37) = 56.56%
If you understand what molecular weight (MW or FW) means, then look at the molecular weight of one molecule of mercury (Hg2) and compare that to the molecular weight of an H2O molecule.Which is heavier?
Ah, the molecular weight of 7H2O, or water, is about 126.14 grams per mole. Isn't that just a lovely number? Remember, understanding the molecular weight helps us appreciate the beauty and harmony of chemistry.
Glucose molecules are larger than water molecules.
The molecular weight of water is 18 lb/lbmol.
The electron geometry of a water molecule is tetrahedral even though the molecular geometry is _____. Bent
Water dissolves some molecular compounds because water is a polar molecule.

A molecule weighing 22 units can be constructed with one atom of carbon and four atoms of hydrogen. This is a methane molecule that normally would weigh 16 units. However, if two hydrogens are deuterium (2 units each) and two atoms of hydrogen are tritium (3 units each), the molecular weight comes out to 22 units.
One molecule of water has a total molecular weight of approximately 18 daltons. This weight is calculated by adding the atomic weights of two hydrogen atoms (each 1 dalton) and one oxygen atom (approximately 16 daltons).
The molecular formula of a compound is the number of atoms of each element in one molecule. So in water (H2O), one molecule of water has 2 Hydrogen atoms and one oxygen.
The mass of water will change because when anything become in the solid form so its weight would be increased . For example when we put some water in it so its weight is less but after freezing its weight become increased because it change in to solid form
