Answer:
![\fbox {(2) 4.9}](https://tex.z-dn.net/?f=%5Cfbox%20%7B%282%29%204.9%7D)
Explanation:
Applying the Ideal Gas Equation :
![\boxed {PV = nRT}](https://tex.z-dn.net/?f=%5Cboxed%20%7BPV%20%3D%20nRT%7D)
Finding n :
- n = 64 g / 32 g/mole (<u>Oxygen is diatomic</u>)
- <u>n = 2 moles</u>
Solving for P :
- P = 2 × 0.0831 × 300 / 10 (<u>Temp. should be converted to K</u>)
- P = 60 × 0.0831
- P = 4.9
∴ The pressure inside the flask in bar is 4.9.
