Question

What volume will 5.6 moles of sulfur hexafluoride

Answer 1

Answer:

19.6 L SF₆

Explanation:

To find the volume, you need to use the Ideal Gas Law:

PV = nRT

In this equation,

-----> P = pressure (atm)

-----> V = volume (L)

-----> n = moles

-----> R = Ideal Gas constant (0.08206 atm*L/mol*K)

-----> T = temperature (K)

After converting the temperature from Celsius to Kelvin, you can plug the given values into the equation and simplify to find "V".

P = 9.4 atm                               R = 0.08206 atm*L/mol*K

V = ? L                                      T = 128 °C + 273.15 = 401.15 K

n = 5.6 moles

PV = nRT

(9.4 atm)V = (5.6 moles)(0.08206 atm*L/mol*K)(401.15 K)

(9.4 atm)V = 184.3429

V = 19.6 L
