^{-2}kg of nitrogen is expanded isothermally and reversibly at 300 K from 15.15 *10^{5}Nm^{-2}when the work done is found to be - 17.33 kJ. find the final pressure.pls show log calculations

(molar mass = 30) at 300 K is

a. -187 kJ

b. 18.7 kJ

c. 6.234 kJ

d. -6.234 kJ

for a particular reaction, the system absorbs 6kJ of heat and does 1.5 kJ of work on its surroundings. Calculate change in internal energy and enthalpy of system.

please give me the ans as soon as you can.

pressure of 304 cm of Hg.

. As a result of the reaction, a piston is pushed

out through 10 cm against an external pressure of 1.0 atm. Calculate the work done by the system.

types of processes of thermodynamics are not given in study material?

H

4.4*10of certain matter is converted into 1 mol as following^{-2}kgn=[4.4*10

^{-2}(kg)] totaldividedby [44*10^{-3}(kg mol^{-1})]=1 moli.e.[4.4*10

^{-2}(kg)] / [44*10^{-3}(kg mol^{-1})]=1 molBut how did they do that? pls explain as soon as.

But how 2*760/760*200/1000 came.

please explain.
