8.06 g of M9SO4 is placed into 100.0 mL of water. The water's temperature increases by 6.70°C. Calculate AH, in kJ/mol, for the dissolution of MgSO4. (The specific heat of water is 4.18 J/g-°C and the density of the water is 1.00 g/mL). You can assume that the specific heat of the solution is the same as that of water.

**Problem:**

8.06 g of MgSO₄ is placed into 100.0 mL of water. The water's temperature increases by 6.70°C. Calculate ΔH, in kJ/mol, for the dissolution of MgSO₄. (The specific heat of water is 4.18 J/g·°C and the density of the water is 1.00 g/mL). You can assume that the specific heat of the solution is the same as that of water.

**Interface Explanation:**

Below the problem statement, there is an input area labeled "kJ/mol" with a numerical keypad. The keypad includes numbers 0-9, a decimal point button (.), a plus/minus button (+/-), a multiply by 10x button (x 10□), a clear button (C), and a delete entry button (←).

This setup is designed for users to input their calculated value for ΔH in kJ/mol. 

The numerical keypad allows for easy and precise entry of numerical answers, accommodating calculations that require scientific notation or adjustments for precision.
