AP Chemistry Unit 1 Sections 1.3 and 1.4 You Might Also Like Imagine a reaction that results in a change in both volume and temperature, as shown in the diagram below. A sample of pure calcium fluoride with a mass of 15.0 g contains 7.70 g of calcium. How much calcium is contained in 45.0 g of calcium fluroride? A student weighs out 14.9 mg of vanadium. How many moles are in the sample? How many moles and how many atoms of zinc are in a sample weighing 34.9 g? Calculate the molar heat of fusion of this substance in kJ/mol 300g of this unknown substance
