Answer:
Final pressure = 0.77atm
Explanation:
The concept used to approach this question is the Ideal gas equation
PV = nRT
where P = pressure
V = Volume
n = number of mole or amount of substance
R = ideal gas constant
T = Temperature in Kelvin
- from the parameters given ; mass = 391g
- Temperature = 695 ∘C = 695 + 273 = 968K
- number of moles = mass/molar mass
- molar mass of CO2 = 12 + 2x16 = 44g/mol
- number of moles = 391g/44g/mol = 8.886mol
plugging into the equation to get the final pressure,
- P = nRT/V = 8.886 x 0.0821 x 968 / 0.770
