Question

zaxoanl · Answer

A cylinder with a moveable piston contains 214mL of nitrogen gas at a pressure of 1.26atm and a temperature of 296K .What must the final volume be for the pressure of the gas to be 1.59atm atm at a temperature of 331K ?


Ammonium nitrate decomposes explosively upon heating according to the balanced equation:
2NH4NO3(s)→2N2(g)+O2(g)+4H2O(g)
Calculate the total volume of gas (at 29∘C and 749mmHg ) produced by the complete decomposition of 1.32kg of ammonium nitrate.

For the First question use the formula P1XV1/T1 = P2XV2/T2....
Plug in the initial values and final values given in the question and solve for V2.
P1= 1.2atm         P2= 1.59atm
V1= 0.214L         V2 = ?
T1 = 296 K          T2 = 331K|dw:1406450206386:dw|
