Question
An element ‘A’ reacts with the compound BO3 to produce A3O4 and B2O3. The number of moles of A3O4 produced if 1 mole each of A and BO3 are allowed to react is
Options
A.3
B.1
C.1/3
D.2/3
Solution
9A + 8BO3 → 3A3O4 + 4B2O3
9 mole 3mole
(L.R.)
∴ 1 mole $\frac{3}{9} = \frac{1}{3}\text{ mole}$
