Answer:
Explanation:
1) Data:
a) n = 0.540 mol
b) V = 35.5 liter
c) T = 223 K
2) Formula:
- Ideal gas equation: PV = nRT
Where,
- P = pressure
- V = volume
- n = number of moles
- T = absolute temperature (kelvin scale)
- R = universal gas constant = 0.08203 atm-liter/K-mol
3) Calculations:
PV = nRT ⇒ P = nRT/V
P = 0.540 mol × 0.08206 atm-liter/K-mol × 223 K / 35.5 liter
P = 0.0443 atm (you must use 3 significant figures).
