## How many moles are in 9 grams of water?

Water has 18 grams per mole so 9 grams is **0.5 moles** of water.

## How many moles are there in 9g of H2O?

= **0.5 Moles** of H2O .

## How many moles are there in 10 grams of water?

1 mole of water weighs 18g. **10/18** moles = 10/18 * 6 * 10^23 number of molecules = 3.33 * 10^23 molecules of water. Each molecule of water has 3 atoms, so the total number of atoms in 10g of water is 3*3.33*10^23 = 10^24.

## How many water molecules are in 9 grams of water?

= **3.** **011 x 10^23**.

## What is the mole of 20 gram of water?

Hence,number of moles in 20g of water is **1.11111**……

## Which one has more molecules 9g of water and 9g of sugar?

Answer: **9 g of water has more** molecules. According to avogadro’s law, 1 mole of every substance weighs equal to molecular mass and contains avogadro’s number of particles.

## How many moles of are there in 1000 g of water?

Now 18g of H20 is equivalent to 1 mole. Hence, 1000g of it would be equal to 1000/18 moles. This comes out be **55.55 moles**. Thus 1 kg of water or ice has 55.55 moles of H20.

## How many grams is 25 moles of water?

1 Expert Answer

Hydrogen has an atomic weight of 1; and oxygen has an atomic weight of 16 (check the periodic table for the atomic weights). So, one mole of water has a mass of 16 +1+1 = 18 grams. So, if one mole has a mass of 18 grams, 25 grams would have a mass of **25** grams/ 18 grams per mole or 1.39 moles.
