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

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.

Water (chemical formula: H2O) is a transparent ... since hydrogen and oxygen each have 3 isotopes, there exist 18 possible molecular weights for water.

9 янв. 2020 г. · Molecular formula of water is H2O. Atomic mass of H=1 u and atomic mass of O=16 u. Thus, molecular mass of H2O=2×1+16=18 u.

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 ...

6 июл. 2016 г. · Water - H2O - consists of 2 Hydrogen atoms and 1 Oxygen atom, so its molecular mass is (2 x 1) + 16, which equals 18 grams.

The molecular mass of water (H2O) is A = 18. In water, one molescule has 10 protons, in which eight from oxygen atom as ...
