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

$R_{Px$ / $R_Ne}$ = $\sqrt{Mr(Ne)/Mr(Px)}$ =0,404

0,404= $\sqrt{20,18/30,97*x}$

$0,404^{2}$ =20,18/30,97*x

X=20,18/30,97*0,163

X=4

There are 4 atoms of P in the molecule
