1 mole of water weighs-H-1.008x2 + O-16.00=18.016. 18.016grams/moles*2.5 moles=45.04 grams.
Now, atomic mass of h20 = 1+1+16 = 18 gram So, molar mass of h2o is = 18 gram. The molar mass of chemical compound is represente by gram molecular mass.

The average mass of one H2O molecule is 18.02 amu. The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol.
Examples: Fe, Au, Co, Br, C, O, N, F. You can use parenthesis or brackets []. Finding Molar Mass. Read our article on how to calculate molar 2010-09-19 Hydrogen (H - Standard atomic weight), molar mass Hydrogen (H) is the simplest, lightest, most common and the first developed chemical element in the universe.

14 Sep 2020 Answer:molar mass :- 18.016 g/molExplanation:molar mass of H2O = mass of H × 2 + mass of O = 1.008 × 2 + 16.0 = 2.016 + 16.0 = 18.016
1 mole H 2 O has the same number of molecules as in 18.015 g of H 2 O. Water (chemical formula: H2O) is a transparent fluid which forms the world's streams, lakes, oceans and rain, and is the major constituent of the fluids of organisms. As a chemical compound, a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water is a liquid at standard ambient temperature and So, For determine the molar mass of h20 add both atomic mass. Now, atomic mass of h20 = 1+1+16 = 18 gram.
