Explanation / Answer

Using the link given: What is the change in temperature when 3 grams of sodiumchloride is dissolved in 100 mL of water? The change in temperature is - 0.48 C. The negative sign is because the temperature reduces. . What is the change in temperature per gram when 3 grams ofsodium chloride is dissolved in 100 mL of water?
The change of 0.48 C is for 3 g of NaCl. The change in temperature per gram = 0.48 C / 3 = 0.16 C . What is the change in temperature when 5 grams of calciumchloride is dissolved in 100 mL of water?
Change in temperature = +8.49 C Positive sign indicates rise in temperature. . What is the change in temperature per gram when 5 grams ofcalcium chloride is dissolved in 100 mL of water?
Change in temperature per gram = 8.49 C / 5 g = 1.7 C/g
