Question

At STP 101.3 kPa 0 C one mole of Ar gas was collected and was found to occupy a volume of 22.4L What is the value of the gas constant in rounded to the nearest hundredth?

Answer 1

8.31 KPa.L/Kmol

Step-by-step explanation:

From the question given above, the following data were obtained:

Pressure = 101.3 KPa

Temperature (T) = 0 °C = 273 K

Number of mole (n) = 1 mole

Volume = 22.4 L

Gas constant (R) =?

The gas constant can be obtained as follow:

PV = nRT

101.3 × 22.4 = 1 × R × 273

2269.12 = R × 273

Divide both side by 273

R = 2269.12 / 273

R = 8.31 KPa.L/Kmol

Therefore, the value of the gas constant is 8.31 KPa.L/Kmol
