the vapor pressure of ethanol at its normal boiling point would be

1)80 kPa
2)101.2 kPa
3)273 kPa
4)373 kPa

would it be 1 ?

  • Chemistry -

    No. What is the definition of the boiling point. The boiling point occurs at the temperature at which the vapor pressure of the liquid equals atmospheric pressure. So which of the answers is standard atmospheric pressure?

  • Chemistry -

    choice 3 ?

  • Chemistry -

    No. 101.325 kPa is standard atmospheric pressure. In other units it is 760 mm Hg or 1 atmosphere or 14.7 lbs/square foot.
