Sagot :

Yipes
[tex]n=\frac{V}{V_{0}}\\\\ V=48dm^{3}\\ V_{0}=22.4\frac{dm^{3}}{mol}\\\\ n=\frac{48dm^{3}}{22.4\frac{dm^{3}}{mol}}\approx2mol\\\\ n=\frac{m}{M_{r}} \ \ \ \Rightarrow \ \ \ M_{r}=\frac{m}{n}\\\\ m=262g\\ n=2mol\\\\ M_{r}=\frac{262g}{2mol}=131\frac{g}{mol}[/tex]

This element must be xenon.
