Question

Plz help me to find the answer

Answer 1

(1) 1,78 dm3

(2) 63,3 dm3

Step-by-step 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
