Answer:
6.3 atm.
Explanation:
Data obtained from the question include:
Initial pressure (P1) = 6 atm
Initial temperature (T1) = 15°C = 15°C + 273 = 288K
Final temperature (T2) = 30°C = 30°C + 273 = 303K
Final pressure (P2) =..?
Since the volume and number of mole of the hydrogen gas sample is constant, the following equation will used to obtain the new pressure:
P1/T1 = P2/T2
6/288 = P2 /303
Cross multiply
288 x P2 = 6 x 303
Divide both side by 288
P2 = (6 x 303) /288
P2 = 6.3 atm
Therefore, the new pressure of the hydrogen gas sample is 6.3 atm.
