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

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.

What is the mass in grams of one mole of sulfur dioxide SO2?

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
