Question

In winter, after a snowstorm, salt (NaCl) is spread to melt the ice on the roads. How many grams of salt per 1000 g of ice is needed to make it liquid at -2.0 degrees Celsius? One mole of any particle dissolved in 1000 g of water lowers the freezing point of the water by 1.86 degrees Celsius. 

**Transcription:** In winter, after a snowstorm, salt (NaCl) is spread to melt the ice on roads. How many grams of salt per 1000 g of ice is needed to make it liquid at -7.0°C? One mole of any particle dissolved in 1000 g of water lowers the freezing point of the water by 1.86°C. [Input box for grams] Buttons: - Submit Answer - Retry Entire Group (7 more group attempts remaining) - Show Hint **Explanation:** This text is part of an interactive educational activity about freezing point depression, a colligative property. The question asks students to calculate the amount of salt needed to melt ice at a specific temperature by using the known depression in freezing point per mole of solute. The resources available, such as "Show Hint" and potential retries, suggest this is part of a learning exercise to help students understand colligative properties in chemistry.
