Answer:
The pressure occupied is 1, 8 atm.
Explanation:
We use the Boyle´s Mariotte ´s law: for a given mass of gas at constant temperature, the pressure and volume vary inversely proportionally: P1xV1= P2xV2. The unit of pressure is converted to mmHg in atm.
760 mmHg----1 atm
912 mmHg---x= (912 mmHg x 1 atm)/760 mmHg=1,2 atm
P1xV1= P2xV2
P2=P1xV1/V2= 1,2 atm x 12 L/ 8L= <em>1, 8 atm</em>
