White phosphorus melts and then vaporizes at high temperatures. The gas effuses at a rate that is 0.404 times that of neon in the same apparatus under the same conditions-There are 4 atoms of P in the molecule
Explanation:
Ar=30,97g/mol
[tex]R_{Px[/tex]/[tex]R_Ne}[/tex]=[tex]\sqrt{Mr(Ne)/Mr(Px)}[/tex]=0,404
0,404=[tex]\sqrt{20,18/30,97*x}[/tex]
[tex]0,404^{2}[/tex]=20,18/30,97*x
X=20,18/30,97*0,163
X=4
There are 4 atoms of P in the molecule
