Answer to Question #118358 in Chemistry for Belen

Question

A 0.582-mil sample of an ideal gas is at 15degrees Celsius and 81.8kPa. Calculate the volume for the ideal gas as described by the ideal gas law

Answer 1

Solution:

The first step is to convert temperature to Kelvins and pressure to atm:

15°C + 273 = 288 K

81.8 kPa × (1 atm / 101.325 kPa) = 0.8073 atm

The Ideal Gas Law:

PV = nRT

Now we can substitute the conditions into the ideal gas law:

(0.8073 atm) × (V L) = (0.582 mol) × (0.08206 L atm mol^-1 K^-1) × (288 K)

(0.8073 atm) × (V L) = (13.7546 L atm)

V = 17.04 L

Answer: V = 17.04 L
