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.
