Solid compound A decomposes according to the endothermic reaction:
A(s)-->2B(g) + C(g) Kp = 1.08 x 10-4
a) If 50.0 mmol of A(s) is placed in a 6.10-L sealed, evacuated flask at 25°C, calculate the total pressure in the flask at equilibrium.
well i plugged all these into the Pv=nRt formula
P=0.05mol(0.08206)(298K)/6.1L and i get the wrong answer for the pressure
the answer is 9.0x10^-2 Atm how would i get there :S please help thanks !
