Question

analysis: calculate the percent changes in volume after each step of the experiment. our scales are accurate to 0.1 gram, therefore your calculations using mass should be rounded to the nearest tenth or 0.1 gram. % change in mass = (final mass - initial mass)/ initial mass × 100 % = (__ / __) × 100 % data table c: place the percentages in the table below: (2 points) % change in water % change in salt water gummi bears tap water distilled water bear

Explanation:

Step1: Recall the percentage - change formula

The formula for percentage change in mass is $\text{% Change in mass}=\frac{\text{Final mass}-\text{Initial mass}}{\text{Initial mass}}\times100$.

Step2: Calculate for each solution

For each of the solutions (Gummi Bears in Salt Water, Tap Water, Distilled Water Beer), you would need to know the initial mass and the final mass of the Gummi Bears. Let the initial mass be $m_i$ and the final mass be $m_f$. Then the percentage - change in mass for a particular solution is $\text{% Change}=\frac{m_f - m_i}{m_i}\times100$.

Since no actual mass values are given in the problem statement, we can't provide numerical answers. But the general steps to calculate the percentage change in mass for each case are as above.

Answer:

The formula to calculate the percentage change in mass for each solution is $\text{% Change in mass}=\frac{\text{Final mass}-\text{Initial mass}}{\text{Initial mass}}\times100$. For actual values, the initial and final masses of Gummi Bears in each solution need to be substituted into the formula.
