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 ?

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.

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?

choice 3 ?

Hi

To determine the vapor pressure of ethanol at its normal boiling point, we need to find the correct option.

The normal boiling point of a substance is defined as the temperature at which its vapor pressure equals the atmospheric pressure. At sea level, the atmospheric pressure is approximately 101.2 kPa.

Therefore, to find the vapor pressure of ethanol at its normal boiling point, we should choose option 2) 101.2 kPa, as this corresponds to the atmospheric pressure at sea level.
