pishuonlain [190]

Answer:

Therefore 373 mole of Al produce 746 mole of water.

Explanation:

Given reaction is

3 Al+3NH₄ClO₄→Al₂O₃+AlCl₃+3NO+6H₂O

From the above reaction it is clear that 3 mole of Al produce 6 mole of water.

Therefore

3 mole of Al produce 6 mole of water.

1 mole of Al produce \frac{6}{3} mole of water.

373 mole of Al produce \frac{6\times 373}{3} mole of water.

                                      = 746 mole of water.

Therefore 373 mole of Al produce 746 mole of water.
