At `25^(@)C` and 730 mm pressure, 380 mL of dry oxygen was collected. If the temperature is constant, what volume will be oxygen occupy at `760 mm` pressure ?

Options

A. 365 mL
B. 2 mL
C. 10 mL
D. 20 mL

Answer

A

Explanation

As the temperature is constant, Boyle's law is applicable.
`p_(1)V_(1)=p_(2)V_(2)`
`V_(1)=380"mL"p_(1)="730 mm",V_(2)=?`
`p_(2)="760 mm"`
`730xx380=760xxV_(2)`
`V_(2)=(730xx380)/(760)=365"mL"`
