Expert Answer

Step 1

The molar mass of boron trifluoride is 67.82 g/mol. The number of moles (n) of boron trifluoride is calculated in equation (1).

The molar mass of dinitrogen difluoride is 66.01 g/mol. The number of moles (n) of dinitrogen difluoride is calculated in equation (2).

Step 2

The mole fraction of boron trifluoride is calculated below.

Step 3

The relation between degree Celsius (○C)and Kelvin (K) is expressed below.

T(K) = 273 + T(○C)  

Use the above relation and Convert 3.4 degrees Celsius.

T (K) = 273 + 3.4○C

      T(K) = 276.4 K

The partial ...
