## How many moles are in 18 grams of water?

– We can say that 18 grams of water means same as **1 mole** of water , and in this NA Avogadro number of water molecules are present , which means 6.02×1023 molecules.

## How many atoms are in 18 grams of water?

Water has a molar mass of 18.01528 g/mol≈18 g/mol . Since water has a chemical formula of H2O , there will be 2 moles of hydrogen in every mole of water. In one mole of water, there will exist approximately 6.02⋅1023 water molecules. So, there will be a total of 6.02⋅1023⋅2≈**1.2⋅1024 hydrogen atoms**.

## What is the mole of 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 many moles is 18 grams?

It is equal to Avogadro’s number (NA), namely 6.022 x1023. If we have one mole of water, then we know that it will have a mass of 2 grams (for 2 molesof H atoms) + 16 grams (for **one moleO** atom) = 18 grams.

## How many moles are in 18 ml of h2o?

Thus, the mass of the water is 18g. This is the same as the molecular mass of water. Now we can calculate the moles of water present using the below formula. So, the number of moles of water will be [dfrac{{18}}{{**18}} = 1] mole**.

## What is the weight of 18 ml water?

Answer: Desity of water is approximately 1 g/cc . So 18 ml of water weights **18 gm**.

## How many atoms are in 18 grams of oxygen?

**6.022×1023 oxygen atoms**.

## How many atoms are in 18 grams of H2O?

The chemical formula of water is H2O, in water two mole of hydrogen is present and one mole of oxygen is present. So, in a single molecule of water, two mole of hydrogen are present. 18 g of water will contain ⇒1×12.046×1023=**12.046×1023 atoms of hydrogen**.

## How many molecules are in a mole?

The mole is represented by Avogadro’s number, which is **6.022×10 ^{23} atoms** or molecules per mol.

## What is the formula for moles to grams?

In order to convert the moles of a substance to grams, you will need to **multiply the mole value of the substance by its molar mass**.
