Answer:
There are 0,89 moles of nitrous oxide gas in the balloon.
Explanation:
We apply the formula of the ideal gases, we clear n (number of moles); we use the ideal gas constant R = 0.082 l atm / K mol:
PV= nRT ---> n= PV/RT
n= 1,09 atm x 20,0 L /0.082 l atm / K mol x 298 K
<em>n= 0,89212637 mol</em>
<span>Kp = PH2O^2/(PH2O)^2
To calculate SO2 is to have a Kp for the reaction
let x=PSO2=PH2S
Kp= (28/760atm)^2/x^3
x=cube root(0.03684)/Kp=PSO2</span>
