Question

Suppose the elements X and Y combine to form two compounds XY_2 and X_3Y_2. When 0.1 mole of XY_2 weighs 10 g and 0.05 mole of X_3Y_2 weighs 9 g, the atomic weights of X and Y are

MARKS Content Team · Accepted Answer

Correct answer: (A) 40, 30. For XY_2, ∵0.1 mole of XY_2=10 g ∴1 mole of XY_2=100 g and X+2Y=100 ...(i) For X_3Y_2, ∵0.05 mole of X_3Y_2=9 g ∴1 mole of X_3Y_2=180 g and 3 X + 2 Y = 1 8 0 ...(ii) On solving, X= 40 and Y=30.
