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

Explanation: 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.

## How many molecules are in 0.25 moles?

so, 0.25 moles of oxygen there is 6.023/4×10^23 molecules.

## How many molecules of water are there in 1 gram of H2O?

or 1 g of water contains (6.022 x 1023)/ 18 water molecules and the number comes out to be 3.3455 x 1022.

## How many molecules are present in water?

Avogadro’s number tells us there are 6.022 x 1023 molecules of water per mole of water. So, next we calculate how many molecules there are in a drop of water, which we determined contains 0.002775 moles: molecules in a drop of water = (6.022 x 1023 molecules/mole) x 0.002275 moles.

## How many molecules of water are present in half mole of water?

Answer: A mole is about 6.022 * 10^23 of anything. So half a mole of water molecules is 3.011 * 10^23 molecules of water.

## How many molecules of water are in 0.9 grams of water?

3.01×1022 molecules.

01×1023 atoms.

## How many molecules are in a mole of Fe?

Explanation: One mole of anything is 6.022×1023 everythings, including atoms. Multiply the moles Fe by 6.022×1023 atoms/mol.

## How many molecules are in a mole of CO?

Heya !! 1 mole of any substance = 6.022 X 10²³ Molecules. Here, CO contains only Two atoms that is One of C and one of O.

## How many molecules are in 2 moles h2o?

Since one mole is defined as 6.022 x 10^23, and there are two hydrogen per molecule, that would mean that there are exactly 12.044 x 10^23 molecules of hydrogen in one mole of water. Double that for 2 moles, and there are 24.088 x 10^23 hydrogen atoms in one mole of water.

## What is the mole of oxygen?

The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g.

## How many moles is one particle?

The mole, abbreviated mol, is an SI unit which measures the number of particles in a specific substance. One mole is equal to 6.02214179×1023 atoms, or other elementary units such as molecules.
