2 OPTION IS CORRECT!!!!!!!!!!!!!!!!

Answer 2

Answer:

Both A and R are correct and R is the correct explanation of A.

Explanation:

Hydrogen and Oxygen always combine in the ratio of 1:8.

Therefore 1x+8x=9g  

9x=9

X=9/9  

Therefore the mass of hydrogen =1x=1×9/9=9/9g or 1g  

Mass of oxygen =8x =8×9/9=8×1=8g

This fulfills the law of definite or constant propotions.
