## What is the mass of 2 moles?

Just multiply 2 by 31.9988 g because there are two moles of oxygen. So, the answer is **63.9976 g** ..

## How many grams are in two 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 many molecules are in 2.00 moles of 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.

## How many atoms are in 2 moles of H2O?

Answer: of atoms (molecules )÷ avogadro no. 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 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**.

## What is a mole of H2O?

H2O Average atomic mass of H: 1.01 g/mol. Average atomic mass of O: 16.00 g/mol. 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**.

## What is the mass of 2 moles of water molecule?

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 many grams is 2.5 moles of water?

The amount of oxygen in 2.5 moles of water is **40 grams**. The molecular formula of water is H₂O. 1 mole of water contains 1 mole of oxygen.
