The molar mass of water in liquid form is 18.02 g/mol, where hydrogen has a molecular mass of 1.01 g/mol and oxygen has 16 g/mol. Therefore, 2.02 + 16 = 18.02 g/mol. Molar mass is usually expressed in the unit of grams per mole (g/mol). The chemical formula for water is H2O. The molar mass of hydrogegn M(H) is 1.008 g/mol and of oxygen M(O) is 15.999 g/mol, so the molar mass of water is calculated as follows: M(H2O) = 2 x M(H) 1 x M(O) = 2 x 1.008 + 1 x 15.999 = 18.015
1 mole of heavy water = 20,0276 grams
Mass= Moles x Relative Atomic Mass or Relative Formula Mass
R.F.M of heavy water = H= 2x2=4 (2 is the Mass Number of the isotope 3 of Hydrogen x 2 the amount of the element present)
0= 16x1=+16
R.F.M = 20
Mass = Moles x R.F.M
Mass = 1 x 20
Mass = 20,0276 grams
Heavy water (deuterium oxide, D2O).
To calculate its molarity you need two costants. Its density at 25C and its molar mass. These are 1.107 g/cm3 and 20.0276 g/mol
Molarity = (density / molar mass ) x 1000 moles per litre
= 50.78 Molar
The molar mass of a substance is determined by multiplying the subscript for each element times its atomic weight on the periodic table and adding the results. So, for water, (2 hydrogen atoms x 1.00794) + (1 oxygen atom x 15.9994.) = 18.0153 grams.
The molar mass of H2O: H=1.0079 but, since there are two H atom, we must multiply 1.0079x2= 2.0158 O=15.9994 Then, add 2.0158 + 15.9994 = 18.0152
18.02, but this is a rounded number of course. The actual mass is 18.01528
[2H]2-water or D2O heavy water: molar mass = 20.04 g/mol
A water molecule has two hydrogen atoms attached to an oxygen atom. Their atomic masses are 1 and 16 respectively. So the molecular mass of water is 16+1x2=18u.
it is 18.0153 g/mol
The molar mass of water is 18 g/mol.

The atomic mass, in grams, is the mass of one mole of atoms.
This is the third element Lithium: 6.94 g is the mass of 1 mole Li. The mass in grams of one mole of any element is exactly its atomic mass (in a.m.u.)
A normal water molecule weighs roughly 18 Amu's, so one mole of water weighs 18 grams. -KRogersaurus

The atomic mass, in grams, is the mass of one mole of atoms.
Gold, as it has the higher molar mass.
This is the third element Lithium: 6.94 g is the mass of 1 mole Li. The mass in grams of one mole of any element is exactly its atomic mass (in a.m.u.)

32 grams, you can find the mass of one mole of any element by looking at its atomic mass eg chlorine has Atomic mass of 35.5 so the mass of one mole of chlorine is 35.5 grams.
One mole of 12C has a mass of 12.00000 grams (exactly, by definition).One mole of 13C has a mass of 13.00335 grams.One mole of 14C has a mass of 14.00324 grams.One mole of natural carbon - i.e. a sample with the ratio of isotopes equal to that in nature - has a mass of 12.0107 grams.

HI, A MOLE IS MOLECULAR MASS. MOLECULAR MASS OF SODIUM IS 23. HENCE, 1.22 MOLE = 1.22*23 = 28.60
28.086 g + 12.011 g = 40.097 g
By definition, one mole would be the same as the atomic mass or molecular mass. You take the number of moles and multiply it by the molecular mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will just be the molecular mass. The molecular mass is the atomic masses of the elements in the compound added together.S- 32.1O- 16.0SO- 48.1 grams in one mole
