Crank

Answer:

The answer is " $\bold{6.26 \times 10^{24} \ molecules \ NH_3}\\\\$ "

Explanation:

1-mole molecules as per Avogadro number $= 6.02 \times 10^{23} \ molecules\\\\$

1-mole $NH_3 \to 6.02 \times 10^{23} \ molecules\\\\$

$10.4 \ moles \ of \ \ NH_3 :$

$\to \frac{ 6.02 \times 10^{23} \ molecules }{ 1 \ mole\ NH_3} \times 10.4 \ mole \ NH_3\\\\ \to 6.02 \times 10^{23} \ molecules \times 10.4\\\\\to 62.608 \times 10^{23} \ molecules \\\\\to 6.26 \times 10^{24} \ molecules \ NH_3\\\\$
