Step 1
1 of 5

Given information:

The density of a mixture of fluorine and chlorine gases $d = 1.77 \mathrm{g/L}$

The temperature $T = 14 ^{\circ}\mathrm{C} = (14 + 273) \mathrm{K} = 287 \mathrm{K}$

The pressure $P = 0.893 \mathrm{atm}$

Ideal gas constant -$R = 0.0821\ \mathrm{L \cdot atm / K \cdot mol}$

Let us determine the mass percent of the gases.
