WebCooling by solar energy is one of the key solutions to the global energy and environmental degradation issues. Solar liquid desiccant based on evaporative cooling is proposed as an eco-friendly alternative to the conventional vapour compression systems due to its huge untapped energy savings potential. WebAnhydrous CaCl2 is used as a desiccator. It removes water from the atmosphere within the desiccator to form a hydrate. A 16.43g CaCl2 sample has a mass of 21.75g after being left in a desiccator for several weeks. What is the formula of the hydrated CaCl2 salt? Show your calculations.
