Question
Students use gummy bears to represent sales in the gummy bear osmosis lab after obtaining an initial mass for each gummy Bear the gummies were soaked for 24 hours in different solutions and then dried and mast the solutions included distilled water tap water 20% sugar solution and 40% salt solution after 24 hours the percent change of each gummy bear was calculated and is shown below distilled water plus 320%, tap water plus 200%, 40% salt solution minus 60%, 20% sugar solution plus 85% based on the data which gummy bear was in the salt solution and what was the tenicity of that solution hypotonic hypertonic hypertonic or hypotonic ABC or d a hypotonic b hypertonic c hypertonic or d hypotonic thank you c is seems to be shrunk a b and d are swelled

To determine which gummy bear was in the 40% salt solution and the tonicity of that solution, we must first understand the behavior of the gummy bears when placed in different solutions.
1. **Distilled Water (Hypotonic)**: The gummy bears in distilled water experienced a percent change of +320%. This is indicative of a hypotonic solution, where water moves into the gummy bears, causing them to swell.
2. **Tap Water (Hypotonic)**: A +200% change shows that the gummy bear also swelled in tap water, which is also hypotonic.
3. **40% Salt Solution (Hypertonic)**: The gummy bear in the 40% salt solution had a percent change of -60%. This negative change indicates that the gummy bear lost mass because water moved out of it into the surrounding hypertonic solution (higher concentration of solutes), causing it to shrink.
4. **20% Sugar Solution (Hypotonic)**: The +85% change shows that the gummy bear also swelled in the 20% sugar solution, as it is hypotonic compared to the gummy bear.
From this analysis, we determine that:
- The gummy bear in the **40% salt solution** (which led to a mass decrease) was the one that shrank (-60% change).
- The **tonicity of the 40% salt solution** is **hypertonic** relative to the gummy bears because it caused them to lose water.
Thus, the answer is:
- The gummy bear in the salt solution is the one that shrank (c), and the tonicity of that solution is **hypertonic**.
