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. 449 mL
C. 569 mL
D. 621 mL

Answer

A

Explanation

At constant temperature `P_(1)V_(1) = P_(2)V_(2)`
`730 mm xx 380 mL = 760 mm xx V_(2)`
or `V_(2) = (730 xx 380)/(760) mL = 365 mL`
