Solid white P melts then vaporizes at high temperatures. Gaseous white P effuses at a rate that is 0.404 times that of neon in the same apparatus under the same conditions. How many atoms are in a molecule of gaseous white phosphorus?
Answered by bobpursley
.404 = sqrt (atomicmassNe/molcmassPx)

solve for the molemass of P

then, number atoms=molemassP/atomicmassP
