When 5 g of NH₄ClO₄ is added to 100 mL of water in a calorimeter, the temperature of the solution formed decreases by 3°C. If 5 g of NH₄ClO₄ is added to 1000 mL of water in a calorimeter initially at 25°C, the final temperature of the solution will be approximately: a) 22.5°C b) 23.0°C c) 23.5°C d) 24.0°C
