## What is the mass of 3 moles of water?

similarly 1 mole of water is equivalent to molecular mass of water x 3 that is 18×3=**54 gram**.

## How many moles are in one gram of water?

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 many moles are there in 5 grams of water?

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

## Is 1g 1 mole?

Ans: 1 mole: It is equal to Avogadro number of atoms. **It is equal to atomic weight in grams**. Ex: 1 mole of sodium is equal to 6.023 * 10²³ number of atoms.

## How many grams are in 2 moles of water?

It is equal to Avogadro’s number (NA), namely 6.022 x10^{23}. If we have one mole of water, then we know that it will have a mass of 2 grams (for 2 moles of H atoms) + 16 grams (for one mole O atom) = **18 grams**.

## How do you find moles of water?

As in the given question we have to calculate how many moles are present in the 25 grams of water and for this we have to **divide the given weight of water by the molecular weight / mass of water**. Hence, 1.38 moles (mol) are present in 25 grams of water.

## How many moles are in a gram?

Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = **0.666** moles.

## How many grams are in 5 moles of h20?

From this you can see that 5 moles of hydrogen gas would react with 2.5 of the available 3 moles of oxygen gas, to form 5 moles of water. The molar mass of water is 18 g/mol, so you would end up with 5 x 18 = **90 g** of water.
