A)5.30 atm
B)6.19 atm
C)0.189 atm
D)0 atm
E)The temperature of a gas at 0 °C is undefined

We can use the combined gas law which states that P1V1/T1 = P2V2/T2. We can assume that the volume remains constant, so V1 = V2. We can also assume that the amount of gas remains constant, so we can cancel out the V's. Rearranging the formula gives us P2 = (P1*T2)/T1. Plugging in the given values, we get P2 = (5.73 atm * 273 K)/(295 K) = 5.30 atm.
