## How much is a mole of water?

Thus, for example, one mole of water (H_{2}O) contains 6.02214076×10^{23} molecules, whose total mass is **about 18.015 grams** and the mean mass of one molecule of water is about 18.015 daltons. The mole is widely used in chemistry as a convenient way to express amounts of reactants and products of chemical reactions.

## What is the volume of one water molecule in ML?

The gram molecular mass of water is 18.02. Thus volume occupied by 1 H2O molecule is **2.99 ×10-23 ml**.

## What is the value of 1 mole?

The value of the mole is equal to **the number of atoms in exactly 12 grams of pure carbon-12** (12 g C = 1 mol C atoms = 6.022 × 10^{23} C atoms).

## What is meant by 1 mole?

A mole corresponds to **the mass of a substance that contains 6.023 x 10 ^{23} particles of the substance**. The mole is the SI unit for the amount of a substance. Its symbol is mol. By definition: 1 mol of carbon-12 has a mass of 12 grams and contains 6.022140857 x 10

^{23}of carbon atoms (to 10 significant figures). Examples.

## What is mass of 2.5 moles of co2?

2.5 mole of co2 = 2.5 x 4.4 = **11g**.

## What is the formula for moles to grams?

In order to convert the moles of a substance to grams, you will need to **multiply the mole value of the substance by its molar mass**.

## What is the volume of water in a molecule?

The volume of one water molecule is **2.99×10-23cm3** .

## How do you find actual volume?

Subtract the mass of the container from the mass of the substance and container to calculate the mass of the substance (mass of substance = mass of container and substance – mass of container). Calculate the volume of the substance by **dividing the mass of the substance by the density (volume = mass/density)**.

## What is the volume of a molecule?

Molecular volume based on molecular mass was calculated using the equation(9.2)**VC=M0/N0V1+dV2where** M0 is the molecular mass, N0 is Avogadro’s number, V1 and V2 are the partial specific volumes of particle (0.74cm3/g) and water (1cm3/g), respectively, and d is the extent of protein hydration (taken as 0.4g water/g …
