Question
The ideal gas equation is PV=nRT where P is pressure, V is volume, n is the number of moles, R is a constant, and T is temperature. You are told that a sample of gas has a pressure of P = 831 torr , a volume of V = 5160 mL , and a temperature of T = 298 K . If you use R = 8.206×102 Latm/(Kmol) , which of the following conversions would be necessary before you could find the number of moles of gas, n, in this sample? Check all that apply.
Check all that apply. Convert the pressure to atmospheres (atm). Convert the pressure to pascals (Pa). Convert the volume to cubic meters (m3). Convert the volume to liters (L). Convert the temperature to degrees Celsius (C). Convert the temperature to degrees Fahrenheit (F).
Explanation / Answer
Convert the pressure to atmospheres (atm)
Convert the volume to liters (L).
pressure of P = 831 torr = 1.0934 atm
a volume of V = 5160 mL = 5.16 L
, and a temperature of T = 298 K .
If you use R = 8.206×102 Latm/(Kmol)
P V = n R T
1.0934 x 5.16 = n x 0.08206 x 298
n = 0.231
number of moles = 0.231
