Question

The no. Of moles of B required to produce 2.5 moles of AB4 according to equation A+4B--- AB4

Answer 1

1 mole of AB4 requires 4 moles of B
so 2.5 requires
2.5x4/1=10 moles of B

Answer 2

Answer: Number of moles of B required are 10 moles.

Explanation:

For the following given reaction:

$A+4B\rightarrow AB_4$

By Stoichiometry of the reaction:

1 mole of $AB_4$ is produced by 4 moles of B

So, 2.5 moles of $AB_4$ will be produced by = $\frac{4}{1}\times 2.5=10$ moles of B

Hence, the number of moles of B required are 10 moles.
