Determine the temperature (in K) of 0.6 moles of gas contained in a 1.7 L vessels at a pressure of 154.2 kPa.

51.6K

Explanation:

Given parameters:

number of moles = 0.6moles

Volume  = 1.7L

Pressure  = 154.2kPa

Unknown:

temperature = ?

Solution

The ideal gas law is best used to solve this kind of problem. The law combines Boyle's law, Charles's law and Avogadro's law.

         PV = nRT

wherre P = pressure in atm

           V = volume in dm³ or L

           n = number of moles

            R = gas constant

         T = temperature in kelvin

Since T is the unknown, we make it the subject of the expression;

             T =

            1atm = 101325Pa

             x atm  = 154.2 x 10³Pa

         x  =  = 1.52atm

T =   =   = 51.6K

the answer is b & c i believe : )
