How many moles of gas occupy 22.4 liters at 27 Celsius degrees and 0.50 atm of pressure?
Thanks for the gas law question.
In order to solve this problem, we can use the Ideal Gas Law.
PV = nRT
Pressure needs to be in atmospheres (.50 atm)
Volume needs to be in liters (22.4 L)
n is the number of moles (and your unknown in this particular question)
R is the universal gas constant (R = .08206
T is the temperature in K (oC + 273 = K, so 27oC + 273 = 300. K)
(.50 atm) ( 22.4 L) = n (.08206
Please do the math and check your answer below:
The number of moles (n) is .45 moles. This number is rounded to the correct number of significant figures.
Have fun with the gas calculations!!
