The liquid with a vapor pressure of 850 torr at 75 °C would exist as a gas at 75 °C and 1 atm pressure.
The liquid with a vapor pressure of 850 torr at 75 °C is a gas. Liquids exist under conditions where the vapor pressure of the liquid is lower than the external pressure. Since the vapor pressure of this liquid is higher than the atmospheric pressure of 1 atm, the substance will exist as a gas at 75 °C and 1 atm pressure.
It is a liquid , 850 torr = 1.11850=atm pressure .
Reason:
so the pressure is still the same, soit the temperature.
Hence, the substance is still a liquid as per the information given .
