Step 6: Calculate - Using the given atomic masses and the number of atoms in one water molecule, the calculated molar mass of H₂O is approximately 18.016 g/mol.

i) H2O: The molecular mass of water, H2O = (2 × Atomic mass of hydrogen) + (1 × Atomic mass of oxygen) = [2(1.0084) + 1(16.00 u)] = 2.016 u + 16.00 u

27 окт. 2015 г. · 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 ...

Molar mass of water is H 2 O = 2 × 1 + 16 = 2 + 16 18 g mol - 1 Therefore, molar mass of water is 18 g mol - 1.

Molar mass of the one mole of water = 2 + 16 = 18 gram per mole. - Therefore the molar mass of one mole of water is 18 gram per mole. Note: We can calculate ...

7 нояб. 2023 г. · The molar mass of water is 18.0 g/mol. In 9 grams of water, there are 0.5 moles, which corresponds to 3.011 x 10²³ molecules.

6 июл. 2016 г. · Molecular mass of water is 2 × atomic mass of Hydrogen + atomic mass of oxygen which is equal to 2 × 1 + 16 = 18 amu.

Enter a chemical formula to calculate its molar mass and elemental composition. Molar mass of H 2 O (Water) is 18.01528 ± 0.00044 g/mol.
