Answer:
Pure water obtained from different sources such as river, well, spring, sea etc. always contain hydrogen and oxygen combined in the ratio 1:8 by mass.
A chemical compound always contains elements combined together in same proportion by mass, it was discovered by French chemist, Joseph Proust (1799).
This illustrates the law of definite proportions.
Thus, both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
