Answer: 0.5 atm
Explanation:
O2 is the chemical formula for molecular oxygen.
Given that,
Original pressure of O2 (P1) = 1 atm
Original volume of oxygen O2 (V1) = 75L
New pressure of O2 (P2) = ?
New volume of O2 (V2) = 2V1
i.e (2 x 75L)
= 150L
Since pressure and volume are given while temperature is held constant, apply the formula for Boyle's law
P1V1 = P2V2
1 atm x 75L = P2 x 150L
75 atm•L = 150L•P2
Divide both sides by 150L to get P2
75 atm•L / 150L = 150L•P2/150L
0.5 atm = P2
Thus, the new pressure of 02 is 0.5 atmosphere
