When gasses F2 and solid I2 are heated to high temperature, the I2 sublimes and gasses iodine heptofluride forms 2.7x10^2 torr of T2 and 3.8 g of solid I2 are put in to a 2.5 L Container at 2.5x10^2 K and container is heated to 5.5 x 10^2 K A what is the final pressure in atms? what is the partial pressure of the I2 gas?
