Answer:
The new pressure of the nitrogen gas is 2, 53 atm
Explanation:
We use te Boyle´s Mariotte law: for a certain mass of gas, at constant temperature, the pressure and volume vary inversely proportionally. We convert the unit of pressure in Torr into atm:
760 Torr---1 atm
480 Torr---x= (480 Torrx 1 atm)/760 Torr=0,632 atm
P1xV1= P2xV2
P2= (P1xV1)/V2= (0,632 atm x 2,0 L)/0,50 L=2,53 atm
