How would you calculate the molar mass of water? - Socratic
Oct 27, 2015 · It is 18 g/mol. One mole of H_2O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom. Mass of 1 mole of Hydrogen atoms= 1 g /mol Mass of 1mole of Oxygen atoms = 16 g/mol Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2 g/mol. Mass of one mole of Oxygen atoms = 1 x 16 g /mol Mass of one mole of water = 2 g/mol + 16 g/mol = 18 …
What is the approximate mass of one water molecule? - Socratic
Oct 29, 2015 · You can determine that by using the molar mass in "g/mol" of the water molecule and converting so that you get the absolute mass in "g". The molar mass is "MM"_("H"_2"O")" = 18.015 g/mol". If you don't remember that, you can also look it up on Wikipedia, or refer to a periodic table and add up the molar masses of two hydrogen atoms and one ...
What is the mass of one mole of heavy water? - Answers
May 30, 2024 · 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 ...

Nov 21, 2023 · When dividing mass of water (in grams) by molar mass of water (18.02 g/mol), grams cancel out so the unit of moles is left. 4. Convert the mass of anhydrate to moles, with the following equation:
What is the molar mass of water? - Socratic
Jun 18, 2017 · A water molecule contains 3 "atoms". These 3 "atoms" constitute 1 "water molecule". A "water molecule" contains 3 "atoms": 2xxH, and 1xxO. That is, those 3 atoms, when appropriately chemically bound, constitute a water molecule. We know that 18.01*g of water contains N_A water molecules, where N_A="Avogadro's number"=6.022xx10^23*mol^-1, and …
How do you calculate the molar mass of heavy water?
Aug 1, 2016 · Simply use the molar mass of deuterium, 2.0*g*mol^-1 For deuterium oxide, ""^2H_2O, D_2O, simply add up the molar masses of each element: (2xx2.014+15.999)*g*mol^-1 ~= 20.0*g*mol^-1. Deuterium oxide is relatively cheap, certainly it is cheap as deuterated solvents go. It is commonly used to introduce a deuterium label into a compound.
