A 7.40 g sample of solid Ni(CN), ·4H,0 was heated such that the water turned to steam and was driven off. Assuming ideal behavior, what volume would that steam occupy at 1.00 bar and 100 °C? It may be useful to consult the periodic table. volume: L

A student leaving campus for spring break wants to make sure the air in her dorm room has a high water vapor pressure so that her plants are comfortable. The dorm room measures 3.25 m × 4.03 m × 3.04 m and the student places a pan containing 0.580 L of water in the room. Assume that the room is airtight, that there is no water vapor in the air when she closes the door, and that the temperature remains a constant 22 °C. The vapor pressure of water at 22 °C is 19.8 mm Hg. Calculate the pressure that the water vapor would exert if all of the liquid water evaporated. mm Hg Will all of the water in the pan evaporate?

Determine the heat of dissolution, in kJ/mol, of 0.250 mol C2 having a specific heat of 0.82 J/g °C. A 9 g sample of C2 was placed in calorimeter with water weighing 130 g. The initial temperature of the system was 18.6 °C and was allowed to reach thermal equilibrium at a temperature of 23.1 °C. Assume that the calorimeter is a perfect insulator. Report answer with 3 significant figures.
