## 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 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 many molecules is 3 moles?

A mole of anything contains 6.022×1023 individual items of that something. You have 3 moles, so there are **3×6.022×1023 oxygen molecules** .

## How many grams is 5 moles of water?

Answer: Since one mole of water is made of two moles of Hydrogen (1.01 g/mol) and one mole of Oxygen (15.99 g/mol) its mass would be 18.01 g. Five moles of water whould have a mass of **90.05 g**.

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

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 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.

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

One mole of H2O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom. Mass of two moles of Hydrogen atoms = 2x 1 g/mol = **2 g/mol**.
