Answer:
There is a temperature of 111 K required.
Explanation:
Step 1: Data given
Volume of hydrogen gas = 6.34 L
Pressure = 1.52 atm at 298 K
The volume of the gas at a pressure of 0.720 atm is 4.98 L
Step 2:
(P1*V1)/T1 = (P2*V2)/T2
⇒ with P1 = the pressure of the hydrogen gas = 1.52 atm
⇒ with V1 = the volume of the hydrogen gas = 6.34 L
⇒ with T1 = the temperature of the hydrogen gas = 298 K
⇒ with P2 = the changed pressure of the gas = 0.720 atm
⇒ with V2 = the changed volume of the gas = 4.98 L
⇒ with T2= the temperature of the gas at 0.720 atm and 4.98L
(1.52*6.34)/298 = (0.720*4.98)/T2
0.0323 = 3.5856/T2
T2 = 110.88 K ≈111K
There is a temperature of 111 K required.

The isotope is phosphorus-32.
It possesses 15 protons that make it phosphorus, 15 electrons, thus, the charges get balanced, and it is electrically neutral. It has 17 neutrons, so in combination, it has 32 protons/neutrons in the nucleus. Therefore, the name is phosphorus-32.
The phosphorus-32 is a beta-emitter with a half-life of 14.3 days that is, used regularly in life-science projects, mainly to generate radiolabeled RNA and DNA probes, like for application in Southern Blots and Northern Blots.
