Question 12 1.09 g of Hy is confined in a 3.00 L container at 25.0°C. What is the pressure in this container in psi? hint: 1 atm = 760 torr = 760 mmHg = 14.7 psi 131 psi 8.90 psi 64.7 psi 4.41 psi
4. In a steel container of 20.0 L, at a temperature of 25.0°C, we have a mixture of F2(g) and Cl2(g). The partial pressure of F2(9) is 6.77 atm and that of C2(g) is 2.44 atm. The following reaction takes place: 5 F2(g) +C2(9)2 CIF(g). What mass of CIFs(g) can be produced? If all of the limiting reagent were to react, what would be the partial pressure of the excess reagent? The volume is fixed at 20.0 L and the...
