Question

At `25^(@)C` and `730 mm` pressure, `730 mL` of dry oxygen was collected. If the temperature is kept constant what volume will oxygen gas occupy at `760 mm` pressure?
A. `701 mL`
B. `449 mL`
C. `569 mL`
D. `621 mL`

Answer 1

`P_(1)=730 mm`
`V_(1)=730 mL`
`V_(2)=?`
`P_(2)=760 mm`
`:. P_(1)V_(1)=P_(2)V_(2)`
`V_(2)=(P_(1)V_(1))/(P_(2))=(730xx730)/(760)=701 mL`
