Question

Calculate the number of moles of gas that occupy a 3.45 L container at a pressure of 150 kPA and a tempeature if 45.6.

Answer 1

We have 0.195 moles of gas

Step-by-step explanation:

Step 1: Data given

volume = 3.45 L

Pressure = 150 kPa = 1.48038 atm

Temperature = 45.6 °C

Step 2: Calculate number of moles gas

p*V = n*R*T

n = (p*V)/(R*T)

⇒ with p = the pressure of the gas = 150 kPa = 1.48038 atm

⇒ with V = the volume of the gas = 3.45 L

⇒ with R = the gas constant = 0.08206 L*atm/k*mol

⇒ with T = the temperature = 45.6 °C = 318.75 Kelvin

n = (1.48038*3.45)/(0.08206*318.75)

n = 0.195 moles of gas

We have 0.195 moles of gas
