Answer:
102.0 g/mol.
Explanation:
Aluminum oxide or Al2O3 is a chemical compound composed of 3 Oxygen and 2 aluminum atoms. Naturally, it is present in the form of mineral corundum in crystalline polymorphic forms. It holds significant importance in the preparation of Aluminium metal that is used as a refractory material.
To calculate the molar mass of Aluminum oxide, we will add the molar mass of 2 Al and 3 O atoms.
Since molar mass of Al is: 26.98 g
Molar mass of O is: 16.00 g
Molar mass of Al2O3
= (26.98)2 + (16.00) 3
= 53.96 + 48
= 101.96 g/mol
Since it is mentioned in question to round off the answer upto 4 significant figures, it will make the answer: 102.0 g/mol.
Hope it help!
The 5 branches are organic, inorganic, biochemistry, analytical, and physical. There are different branches because they each apply to different parts of chemistry. For example organic chemistry is the study of carbon compounds and inorganic chemistry is the study of non carbon compounds. You can't just have one type of chemistry because these are very different.

In coordination chemistry,
A coordinate covalent bond also known as a <em>dative bond, dipolar bond, or coordinate bond</em> is a kind of two-center, two-electron covalent bond in which the two electrons derive from the same atom. The bonding of metal ions to ligands involves this kind of interaction.

Answer:
water evaportaes from heat it then turns into a gas then can go into a solid one day and repeat the cycle
Explanation:
Because all matter has density and since air has density then air is matter and plus EVERYTHING is made of matter
