Asubstance has a heat of vaporization of 16.69 kj/mole. at 254.3 k it has a vaporpressure of 92.44 mm hg. calculate its vapor pressure at 275.7 k.

The vapor pressure is 170.6 mmHg.

Explanation:

Given that,

Heat of vaporization = 16.69 kJ/mole

Temperature = 254.3

Pressure = 92.44 mmHg

Temperature = 275.7 K

We need to calculate the vapor pressure

Using relation pressure and temperature

Put the value into the relation

Hence, The vapor pressure is 170.6 mmHg.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
