If $H_{2}$ and $C l_{2}$ enclosed separately in the same vessel exert pressure of 100 and 200 $m m$ respectively, their mixture in the same vessel at the same temperature will exert a pressure of ?

Solution

Dalton's law of partial pressures:
$P_{t o t a l} = P_{1} + P_{2} + P_{3} + . . .$
$P a r t i a l p r e s s u r e = x \times P_{t o t a l}$
where $x=molefraction$
so total pressure is the sum of partial pressures.
but here same mole fraction of gases are not mentioned so it is not sure whether their mixture in the same vessel at the same temperature will exert a pressure of 300 $m m$ .
