Question

If we have 24g of nitrogen how much hydrogen atom is required to form ammonia?

Answer 1

$N_2+3H_2\rightleftarrows 2N{H}_3$

$1$ mole of Nitrogen requires $3$ moles of Hydrogens

$28g$ requies $6g$ Hydrogen.

$24g$ requies $xg$ Hydrogen.

$x=\frac{24\times 6}{28}=\frac{36}{7}=5.14$

$\therefore$ $5.14$ Hydrogen atoms required.
