What pressure will be exerted by 10 moles of hydrogen gas in a 7.5 l cylinder at 20°c? (given: r = 8.314 l∙kpa/k∙mol) 3248 kpa 24360 kpa 324.8 kpa 24.36 kpa 0.2436 kpa

The value of the pressure will be 3248 kPa.

Explanation:

Let the pressure exerted by the gas be P

The volume occupied by the gas = V = 7.5 L

Temperature of the gas = T =20°C = 293 K

(0°C = 273 K)

Number of moles of gases = 10 mol

Using an ideal gas equation:

P = 3248.0026 kPa ≈ 3248 kPa

The value of the pressure will be 3248 kPa.
