Jazmin and Ty did a chemistry experiment in which they dissolved the ionic compound lithium chloride (LiCl) in water. They observed that after mixing 3.0 g of the ionic compound into 20 mL of water, the temperature dropped from 22 °C to 15 °C. Based on these experimental results, it is likely that all of the following would result in a greater temperature decrease

Question
Jazmin and Ty did a chemistry experiment in which they dissolved the ionic compound lithium chloride (LiCl) in water. They observed that after mixing 3.0 g of the ionic compound into 20 mL of water, the temperature dropped from 22 °C to 15 °C.

**Concentration Preparation Examples** In this section, we provide examples to illustrate the preparation of different concentrations of lithium chloride (LiCl) solutions by varying the amount of LiCl and the volume of water used. a. **Using 6.0 g of LiCl and 20 mL of water:** Example demonstrates preparation with a relatively higher amount of LiCl in a larger volume of water. b. **Using 1.0 g of LiCl and 20 mL of water:** Example demonstrates preparation with a lower amount of LiCl in the same volume of water as example 'a'. c. **Using 3.0 g of LiCl and 10 mL of water:** Example demonstrates preparation with a moderate amount of LiCl in a smaller volume of water. d. **Using 6.0 g of LiCl and 10 mL of water:** Example demonstrates preparation with the same amount of LiCl as example 'a' but in a smaller volume of water. These examples help students understand how different concentrations can be achieved by adjusting the quantities of solute and solvent.
