Why is the mass of one mole of water?

Mass of 1 Mole of Water

Water (H2O) is made from 2 atoms of hydrogen and 1 atom of oxygen. … This means 1 mole of hydrogen weighs 1.0079 grams and 1 mole of oxygen weighs 15.9994 grams.

What is the mass of one mole?

The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.

What is a mole of H2O?

H2O Average atomic mass of H: 1.01 g/mol. Average atomic mass of O: 16.00 g/mol. 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.

What is the mass of 2 mole of water?

One mole of H2 O 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. Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.

How many liters are in 1 mole of h2o?

For water, 1 mole = 18 g= 22.4 liter.
