Answer: 4.08%
Explanation:
According to the ideal gas equation:'
Pressure of the gas = 1 atm
Volume of the gas = 10 L
Temperature of the gas = 327°C = (327+273)K = 600K (0°C = 273 K)
Value of gas constant in in kilopascals = 0.0821 Latm/K mol
3 moles of is produced from 2 moles of
Thus 0.20 moles of is produced from = of
Mass of
Thus percent of decomposed is =
4.08 % of decomposed.
