Question

At 27 °C, 3 mole of Bromine gas was found to occupy a volume of 6 Lat a pressure of 380 kPa. What is the value of the gas constant in L.kPa/ mol.K?

Answer 1

Answer: 2.53

Step-by-step explanation: The ideal gas equation is formulated as:

`PV = nRT`

P = Pressure of the ideal gas,

V = Volume of the ideal gas,

n = Total amount of ideal gas that is measured in terms of moles,

R = Gas constant, and

T = Temperature

By rearranging the ideal gas equation we get,

`R = PV/nT`

P = 380 kPa

V = 6 L

n = 3 moles

T = 27+273 = 300 K

Put the value given in this equation:

R = 380 kPa . 6L / 3 mol . 300 K

R = 2.53
