Q. A preweighted vessel was filled with $CO_{2}$ at STP and weighed. It was then evaluated, filled with $SO_{2}$ at the same temperature and pressure and again weighted. The weight of the $CO_{2}$ will be
A) The same as that of the $SO_{2}$
B) Twice of that of the $SO_{2}$
C) Half that of the $SO_{2}$
D) Two third of that of $SO_{2}$
Explanation
(c)
$\frac{M\ wt.of\ CO_{2}}{M\ wt.of\ SO_{2}} = \frac{M_{1}}{M_{2}} = \frac{44}{64} = \frac{11}{16}$
$approx\ = \frac{2}{3}$
