Question

The fuel used to power the booster rockets on space shuttles is a mixture of aluminum metal and ammonium perchlorate. The following balanced equation represents the reaction.. 3Al + 3NH4ClO4 → Al2O3 + AlCl3 + 3NO + 6H2O How many moles of water are produced from 373 mol Al?

Answer 1

its 746 I just took it 

Answer 2

Answer : The number of moles of water produces are, 746 moles

Solution : Given,

Moles of aluminum = 373 moles

The balanced chemical reaction is,

$3Al+3NH_4ClO_4\rightarrow Al_2O_3+AlCl_3+3NO+6H_2O$

From the balanced chemical reaction, we conclude that

As, 3 moles of aluminum react to give 6 moles of water

So, 373 moles of aluminum react to give $\frac{6}{3}\times 373=746$ moles of water

Therefore, the number of moles of water produces are, 746 moles
