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).
An example of a molecule?
A molecule of water, a molecule of hydrogen, a molecule of oxygen, a molecule of sugar... Actually more substances come in form of molecules than in atomic form.
What is the effective atomic number of water?
The effective atomic number of water is approximately 7.42. This value takes into account the contribution of the hydrogen atoms in water in addition to the oxygen atom. It is a way to characterize the overall electron density of the molecule.
How much does one water molecule weight?
The mass of any molecule is equal to the sum of the Atomic Mass Units of all of its constituent atoms. Atomic Mass Unit values may be found on any Periodic Table. In this case, a water molecule consists of two Hydrogen atoms and one Oxygen atom. Hydrogen has a mass of approximately 1 AMU. Oxygen has a mass of approximately 16 AMU. Therefore, the mass of one molecule of water is approximately 18 AMU (or 18.01528 AMU exactly). What does this number mean? If you had exactly 6.022 x 10^23 molecules of water, it would weigh 18 grams.
What you the mass number of H2o?
The mass number of water (H2O) is calculated by summing the atomic masses of its components. Hydrogen has an atomic mass of 1 and oxygen has an atomic mass of 16. Therefore, the mass number of water is 18.

Which one of the following molecule is not tri-atomic?
To determine which molecule is not tri-atomic, we need to identify examples of tri-atomic molecules (which have three atoms) versus those that have a different number of atoms. Common tri-atomic molecules include water (H₂O) and carbon dioxide (CO₂). A diatomic molecule, such as oxygen (O₂), consists of only two atoms, while a tetra-atomic molecule, like methane (CH₄), has four. Therefore, any diatomic or tetra-atomic molecule listed would not be tri-atomic.
What is the mass of a water molecule in atomic mass units?
A normal water molecule weighs roughly 18 Amu's, so one mole of water weighs 18 grams. -KRogersaurus
Why can't we see water?
Molecules are very microscopic, so you would not be able to see a water molecule. This is on an atomic level, by the way.

Can Atomic mass be used to determine molecular mass?
Yes, the accumulation of atomic masses of the atoms within a molecule is the molecule's molecular mass.
What is the effective atomic number of water?
The effective atomic number of water is approximately 7.42. This value takes into account the contribution of the hydrogen atoms in water in addition to the oxygen atom. It is a way to characterize the overall electron density of the molecule.
Who is lightest Hydrogen molecule or methane molecule?
Hydrogen molecule is the lightest because of its atomic mass being less than any other molecule .i.e 1amu (atomic mass unit). Hence Hydrogen molecule is lighter than Methane molecule.

What is a molar mass of a molecule?
The molar mass of a molecule is the sum of atomic weights of the elements contained in this molecule.
What is the atomic mass of 5 water molecules?
The atomic mass of a single water molecule (H₂O) is approximately 18.02 grams per mole, calculated from the atomic masses of hydrogen (about 1.01 g/mol) and oxygen (about 16.00 g/mol). Therefore, the total mass of 5 water molecules can be calculated by multiplying the mass of one water molecule by 5, resulting in about 90.1 grams per mole for 5 molecules. However, since the atomic mass is typically expressed per mole, the mass of 5 water molecules in grams would be significantly less than this value.
