Two solutions are prepared using the same solute:Solution A: 0.14g of the solute dissolves in 15.4 g of t-butanol. Solution B: 0.17 g of the solute dissolves in 12.7 g of cyclohexane. Which solution has the greatest freezing point change? Explain
The two solutions start at a temperature of 25.5°C, and reach a final temperature of 27.8°C. The final, combined mixture has a mass of 51.6 grams and a specific heat of 4.0 J/g°C. Assume that no heat is transferred to the cup or surroundings.
