( begin{aligned} 0 quad 0 cdot 0138 & frac{3}{9} times 1 &=frac{1}{3} text { moleg } end{aligned}=frac{4}{9} )
Thus I mole of A will produce
( frac{1}{3} ) mole ( beta ) 05

OP tion (2) is correct.

# 8. An element A reacts with compound Bo, to produce A204 and B203. The no. of moles of A,O produced if one mole each of A and BO, is reacted, is 3A00 , Agou Boon (1) 3 (2) (4) (4) 1 (3) 2 1
