## How many moles of water are in 50.0 ml of water?

Answer: 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 moles of water are in H2O?

The average mass of one H2O molecule is 18.02 amu. The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of **one mole** of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol.

## How do you find the number of moles of water?

So in order to calculate the number of moles of any substance present in the sample, we simply **divide the given weight of the substance by its molar mass**. Where ‘n’ is the number of moles, ‘m’ is the given mass and ‘M’ is the molar mass.

## How many moles are in 5g of h2o?

**5/18 moles** for 5 grams of water.

## How many moles of water are in 24.3 grams of water?

The answer is **18.01528**. We assume you are converting between grams Water and mole.
