Divide the molar mass of the compound by the empirical formula mass. The result should be a whole number or very close to a whole number. Multiply all the subscripts in the empirical formula by the whole number found in step 2. The result is the molecular formular
<h2>What is chemical binding?</h2>
Chemical bonding helps to joining atoms or molecules together. It is also helps molecules of the same or different substance to get together through joining to each other . Solid , liquid, or gaseous matter can exist in the nature due to chemical bonding .
<h3>How Chemical bonds are formed?</h3>
Bonds form when atoms share or transfer valence electrons. Valence electrons are the electrons in the outer energy level of an atom that may be involved in chemical interactions. Valence electrons are the basis of all chemical bonds.
There are two primary kinds of chemical bonds that keep atoms together:
- Covalent
- Electrovalent/ionic bonds.
Covalent bonds have atoms which share electrons in a chemical bond.
Ionic bonds are formed by the of atoms that have opposite charges
- Sodium chloride, or NaCl, is an example of an ionic bond.
- Another example of an ionic bond is found in lithium fluoride (LiF). Lithium has one electron in its outer shell, and fluorine has seven electrons in its outer shell.

Answer
12
Explanation
We have a balanced chemical equation from the question that depicts the formation of water.
2H2+O2-->2H2O,
We can clearly see from the equation that, the formation of 2 moles of water molecules requires the input of 2 moles of hydrogen and 1 mole of Oxygen.
So indirectly, it tells that the moles of water molecules will be double of the moles of Oxygen molecules used in the reaction.
So if we say that 6 moles of oxygen is used and the reaction is going in such a way that hydrogen is not a limiting reactant, then 12 moles of water will be produced.
Hope it help!
Answer:
Ok:
Explanation:
So grams = mols*MolarMass. Here, MolarMass (MM) = 105.99g which can be found using the periodic table. mols is given to be 0.802. We can then plug in to get that it corresponds to 85.0g.
