Question

Determine the new pressure of a sample of hydrogen gas if the volume and moles are constant, the initial pressure is 6.0 atm, and it is heated from 15°C to 30.°C. PLEASE HELP ASAP! THANK U SO MUCH!

6.3 atm

5.7 atm

12 atm

3.0 atm

Answer 1

6.3 atm.

Step-by-step 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.
