# How many numbers of particles are present in 0 5 mole of water molecule?

Contents

0.5 x 6.022 x 10^23 molecules of water.

## How many molecules are there in 5.0 moles of H2O?

Answer: 5 moles of water will have N=2. 5×6. 023×1023=15×1023 molecules.

## What is the mass of O 5 mole of water molecules?

Mass of 0.5 mole of water is 9g.

## How many particles are there in 1 mole of water?

A mole (mol) is the amount of a substance that contains 6.02 × 10 23 representative particles of that substance. The mole is the SI unit for amount of a substance. Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02 × 10 23 water molecules in a mole of water molecules.

## What is the 0.5 moles of water?

so, mass of 0.5 mole of H2O=18*0.5

=9grams.

## How many molecules is 0.5 moles?

If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 23) Na atoms, or 1.2044 × 10 24 Na atoms. Similarly, if we have 0.5 mol of benzene (C 6H 6) molecules, we have 0.5 × (6.022 × 10 23) C 6H 6 molecules, or 3.011 × 10 23 C 6H 6 molecules. A mole represents a very large number!

## How many water molecules are in 2.5 moles?

1.5×1024 molecules.

## What is the mole of 12 gram of oxygen gas?

Therefore, 12 g of oxygen gas has 0.375 moles.

## What is the mass of 0.1 mole of water?

Gram mole is same as mole. Molecular formula of water is H2O. So, adding the two we get the weight of one mole of water, which is 18g.

## What is the mass of 0.25 mole of water?

1 mole of water weighs equal to the molecular mass of water. Thus the amount of present in 0.25 mole of it is 4.5 grams.

## What is the mole of H2O?

Molar mass H2O = (2×atomic mass H) + (1×atomic mass O) = (2×1.00794) + (1×15.9994) = 18.02 • 1 H2O molecule has a mass of 18.02 amu. 1 mole of H2O molecules has a mass of 18.02 grams.

Avogadro’s number is defined as the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance. It is equal to 6.022×1023 mol-1 and is expressed as the symbol NA. Avogadro’s number is a similar concept to that of a dozen or a gross.

## What is the number of molecules in 0.25 mole of oxygen?

Thus, 0.25 mole of oxygen contains 1.505×1023 molecules.

## What is the mass of 0.5 mole of CO2?

0.5 mole CO2​=0. 5×44=22 gm.

## What is the mass of 0.5 mole of water molecules 9th?

Thus, the mass of 1 mole of water is 18 grams. Thus, the mass of 0.5 mole of water (H2O) is 9 grams.
