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
0,404=![\sqrt{20,18/30,97*x}](/tpl/images/0546/5536/29174.png)
X=20,18/30,97*0,163
X=4
There are 4 atoms of P in the molecule
