Plz help me to find the answer

(1) 1,78 dm3

(2) 63,3 dm3

Explanation:

Boyle's law reads:

p * V = const

(1) First the two given values are inserted:

    2,5 dm3 * 50 kPa = 125

   Then you rearrange the equation according to the volume:

   12,5 / 70 kPa = 1,78 dm3

(2) 50 atm = 5066,25 kPa

     1200 torr = 159,9868 kPa

    First the two given values are inserted:

    2 dm3 * 5066,25 kPa = 10132,5

     Then you rearrange the equation according to the volume:

     10132,5 / 159,98 kPa = 63,3 dm3
