1.	A compound contains 28% of nitrogen and 72% of a metal by weight. 3 atoms of the metal combine with 2 atoms of nitrogen. Find the atomic weight of the metal. (N = 14)
Answer» <html><body><p></p>Solution :The formula of the compound is `M_(2)N_(2)` (M representing the metal) `2 xx `moles of `M= 3 xx` moles of N. <br/>Now if the <a href="https://interviewquestions.tuteehub.com/tag/weight-1451304" style="font-weight:bold;" target="_blank" title="Click to know more about WEIGHT">WEIGHT</a> of the compound is 1 gram <br/> then weight of M = 0.72 <a href="https://interviewquestions.tuteehub.com/tag/g-1003017" style="font-weight:bold;" target="_blank" title="Click to know more about G">G</a> and weight of N=0-28 g. <br/> `:. <a href="https://interviewquestions.tuteehub.com/tag/2xx-1840186" style="font-weight:bold;" target="_blank" title="Click to know more about 2XX">2XX</a>(0.72)/("atomic weight of M") =3xx(0.28)/(<a href="https://interviewquestions.tuteehub.com/tag/14-272882" style="font-weight:bold;" target="_blank" title="Click to know more about 14">14</a>)` . <br/> Atomic weight of the metal =<a href="https://interviewquestions.tuteehub.com/tag/24-295400" style="font-weight:bold;" target="_blank" title="Click to know more about 24">24</a></body></html>
