What is the weight of 2 moles of water?
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.
What is 2 moles 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.
What is mole of water?
A mole is a unit measuring the quantity of anything. Water (H2O) is made from 2 atoms of hydrogen and 1 atom of oxygen. A mole of water molecules would be 2 moles of hydrogen atoms plus 1 mole of oxygen atoms. weight of water = 2(1.0079) g + 15.9994 g. weight of water = 2.0158 g + 15.9994 g.
How do you calculate moles of water?
As in the given question we have to calculate how many moles are present in the 25 grams of water and for this we have to divide the given weight of water by the molecular weight / mass of water. Hence, 1.38 moles (mol) are present in 25 grams of water.
What does 1 mole of water look like?
Thus, for example, one mole of water (H2O) contains 6.02214076×1023 molecules, whose total mass is about 18.015 grams and the mean mass of one molecule of water is about 18.015 daltons, roughly a combined atomic mass number of 18.

How many liters are in 1 mole of H2O?
For water, 1 mole = 18 g= 22.4 liter.
How many molecules of water are there in 2.00 moles of water?
Therefore 2 mole H2O will have 2.4088×10^24 hydrogen atoms. one mole of water contains 6.02 x 1023 molecules of water. But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.
How many moles is 108 grams of H2O?
Converting Between Grams and Moles

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.
