Calculate the pressure exerted by benzene for a molar volume of 1.7 l at 582 k using the redlich-kwong equation of state: p=rtvm−b−at√1vm(vm+b)=nrtv−nb−n2at√ 1v(v+nb) the redlich-kwong parameters a and b for benzene are 452.0 bar dm6 mol−2 k1/2 and 0.08271 dm3 mol−1, respectively. express your answer to two significant figures and include the appropriate units.

Aball tossed vertically upward from the ground next to a building passes the bottom of a window 1.8 s after being tossed and passes the top of the window 0.20 s later. the window is 2.0 m high from top to bottom. what was the ball's initial velocity? the unit vector j^ is directed upward. how far is the bottom of the window from the launch position? how high does the ball rise above the launch position?
