Answer:
Step-by-step explanation:
Here, we want to getthe new pressure
From Boyles' law, we know that the volume of a given mass of gas is inversely proprttional to the pressure at a constant temperature
Mathematically:
where:
P1 is the initial pressure hich is 1.6 atm
P2 is the final pressure which is 744 mmHg (converting to atm by dividing by 760 mmHg, we have the aluea as 744/760 = 0.98 atm
V1 is 45 ml
V2 is ?
Now, the gas expanded from 73. mL to 125 mL
The initial pressure woud now be 0.98 atm
Thus, we have the new pressure as:
