Answer : The partial pressure of and
are, 84 torr and 778 torr respectively.
Explanation : Given,
Mass of = 15.0 g
Mass of = 22.6 g
Molar mass of = 197.4 g/mole
Molar mass of = 32 g/mole
First we have to calculate the moles of and
.
and,
Now we have to calculate the mole fraction of and
.
and,
Now we have to partial pressure of and
.
According to the Raoult's law,
where,
= partial pressure of gas
= total pressure of gas
= mole fraction of gas
and,
Therefore, the partial pressure of and
are, 84 torr and 778 torr respectively.
