Determine the normal boiling point of a substance whose vapor pressure is 55.1 mm hg at 35°c and has a δhvap of 32.1 kj/mol.

389.78681 K

Explanation:

= Initial pressure = 55.1 mmHg

= Final pressure = 1 atm = 760 mmHg

= Boiling point

= Initial temperature = 35°C

= Heat of vaporization = 32.1 kJ/mol

From the Clausius-Claperyon equation

The normal boiling point of the substance is 389.78681 K

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
