The image presents a chemistry problem related to the freezing point depression of ethanol. **Problem Statement:**The freezing point of ethanol \( \text{CH}_3\text{CH}_2\text{OH} \) is -117.30°C at 1 atmosphere. A nonvolatile, nonelectrolyte that dissolves in ethanol is saccharin.- Given: 13.73 grams of saccharin, \( \text{C}_7\text{H}_5\text{NO}_3\text{S} \) (molar mass = 183.2 g/mol), are dissolved in 156.3 grams of ethanol.**Questions:**1. Calculate the molality of the solution.2. Determine the freezing point of the solution.Below the problem statement, there are two input boxes labeled to enter the answers for molality (in mol/kg) and the freezing point of the solution (in °C). Buttons labeled "Submit Answer" and "Retry Entire Group" are provided for input submission, with a note stating that there are 9 more group attempts remaining.There are no graphs or diagrams present in the image.

Electrolytes – A balancing act! A certain amount of each of the biologically important electrolytes is needed in the body. But if some is good, that doesn't mean that more is necessarily better. Too little of the specific nutrient is called hypo-, while too much is called hyper-. The figure below shows the optimal concentration ranges of each of some of the electrolytes for correct biological functioning. Normal Ranges and Disturbances for Common Electrolytes 11 +1 Normal Range of Sodium: 134 to 145 mEg/L Na Hypernatremia: when sodium is higher than the normal range. Hyponatremia: when sodium is lower than the normal range. Br Sodium As Bromine Mg Hypermagnesemia: when magnesium levels are higher than the normal range. 12 +2 Normal Range of Magnesium: 0.70 to 0.95 mmol/L 83.798 Hypomagnesemia: when magnesium levels are lower than the normal range.
