# What is the mass of 1 00 mole of h2o?

Contents

The mass of 1 mole of H2O is approximately 18.015 g. Therefore, the mass of 100 moles of H2O is approximately 1801.5 g.

## So let’s look at the request more closely

The mass of 1 mole of H2O is approximately 18.015 g. Therefore, the mass of 100 moles of H2O is approximately 1801.5 g.

Water, chemically represented as H2O, is a fundamental component of life and plays a vital role in various physical and chemical processes. Its molar mass, also known as molecular weight, is the sum of the atomic masses of all the atoms in a molecule. In the case of water, it is composed of two atoms of hydrogen and one atom of oxygen, with atomic masses of 1.008 and 15.999, respectively. Thus, the molar mass of water is calculated as follows:

Molar mass (H2O) = (2 x 1.008 g/mol of H) + (1 x 15.999 g/mol of O)
Molar mass (H2O) = 18.015 g/mol

Therefore, the mass of 100 moles of H2O is approximately 1801.5 g.

As stated by the famous scientist and philosopher, Aristotle: “Water is a very good servant, but it is a cruel master.”

Here are some interesting facts about water:

• The Earth is sometimes referred to as the “Blue Planet” because 71% of its surface is covered in water.
• Water can exist in three states: solid (ice), liquid (water), and gas (water vapor).
• The structure of water is unique as it forms a hexagonal lattice when it freezes, making it less dense than liquid water.
• Water is considered a universal solvent because it can dissolve so many different types of substances.
• Approximately 60% of the human body is made up of water.
• Water is essential for many bodily functions, including regulating body temperature, transporting nutrients, and removing waste.
• The world’s largest ocean, the Pacific Ocean, covers 30% of the Earth’s surface.
• The Great Barrier Reef, the largest coral reef system in the world, is made up of over 2,900 individual reefs and 900 islands.
• Water is a precious resource, and many parts of the world experience water scarcity due to factors such as drought, pollution, and overuse.

## This video contains the answer to your query

The video explains how to calculate the molar mass of water (H2O), using the molar mass for hydrogen and oxygen from the periodic table, which are 1.01 grams per mole and 16.00 grams per mole, respectively. By multiplying the molar mass of hydrogen by 2 and adding it to the molar mass of oxygen, the molar mass of water is determined to be 18.02 grams per mole.

The molecular mass of water = mass of 1 mole of water = 18g.

One mole of water (H2O) is a unit of measurement that contains 6.023 x 10^23 molecules of water. Each molecule of water is composed of two atoms of hydrogen and one atom of oxygen. Therefore, one mole of water also contains two moles of hydrogen atoms and one mole of oxygen atoms. The mass of one mole of water is 18 grams, which is the sum of the atomic masses of hydrogen and oxygen.

One mole of water contains 6.023 x 1023 molecules. Each H2O molecule has two hydrogen atoms and one oxygen atom. Therefore, in one mole of water (H2O), there are two moles of hydrogen atoms and one mole of oxygen atoms.

Water (H 2 O) is made from 2 atoms of hydrogen and 1 atom of oxygen. A mole of water molecules would be 2 moles of hydrogen atoms plus 1 mole of oxygen atoms.

The molecular formula of water is H 2O The atomic mass of H = 1 The atomic mass of O = 16 In a sense, the formula means H + H + O So… 1 + 1 + 16 = 18 Therefore, the mass of one mole of water = 18 Grams

The molecular formula of water is H 2O The atomic mass of H = 1 The atomic mass of O = 16 In a sense, the formula means H + H + O So… 1 + 1 + 16 = 18 Therefore, the mass of one mole of water = 18 Grams

The molecular weight of water is 18 g/mol. Hence, one mole of water weighs 18 g. One mole of water contains 6.023 × 10^23 water molecules. Mass of one water molecule = 186.023 × 10^23 = 2.988 × 10^-23
