Answer 2

Question

The No. of molecules present in 14 gm of N2 molecules ?

Answer

28 gm of N2 molecules contains = ${\bf 6.023 \: \times \: 10^{23} }$molecules

So, now the 14 gm of N2 molecule will contain half of 28 gm of N2 molecule

$\large{ \frac{\bf 6.023 \: \times \: 10^{23} }{2}} \: \bf$

${\bf = 3.011 \times \: 10^{23} }$

${\bf Answer : 3.011 \times \: 10^{23} \: molecules}$
