Answer:
The volume wuill become 0,5 liters
Step-by-step explanation:
We use Boyle-Mariotte's Law, according to which at constant temperature, the pressure and volume of a gas vary inversely. We convert mmHg into atm:
760mmHg equivalent to 1atm.
P1xV1 =P2xV2
1,00atm x1,00L=2,00atmxV2
V2= (1,00atm x1,00L)/2,00atm=0,5 L
