Dalton's atomic theory taught that all matter composed of atoms (inseparable and cannot be destroyed).
<u>Explanation:</u>
Dalton's atomic theory, the initiative comprehensive approach to explain all matter based on atoms and its properties. He proposed this theory based on the law of mass conservation and constant composition law. The importance of Dalton's atomic theory are:
Everything consists of atoms, which are inseparable elements of matter and cannot be impaired. All element's atoms are identical. Atoms of different elements differ in their sizes and masses. Compounds are created by simply bonding atoms and creating complex atoms (molecules).

I think C But I can't really see it well
Answer:
Number of mole in H2O = 5.4 moles
Explanation:
Given:
Mass of H2O = 97.3 gram
Find:
Number of mole in H2O
Computation:
We know that molar mass of H2O = 18 g/mole
So,
Number of mole = Given Mass / Molar mass
Number of mole in H2O = Mass of H2O / Molar mass of H2O
Number of mole in H2O = 97.3 / 18
Number of mole in H2O = 5.4055
Number of mole in H2O = 5.4 moles
