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.
