Question

At 25°C and 730 mm pressure, 380 ml of dry
oxygen was collected. If the temperature is
constant, what volume will oxygen occupy at 760
mm pressure.​

Answer 1

Answer:

To calculate the new volume, we use the equation given by Boyle's law. This law states that pressure is inversely proportional to the volume of the gas at constant temperature.  

The equation given by this law is:

where,

= initial pressure of gas= 730 mm Hg

 =  initial volume of gas = 380 ml

= final pressure of gas= 760 mm Hg

 = final volume of gas = ?

Putting values in above equation, we get:
