I think it was Penelope. The size of the shoe had to have been 9.8 because if your shoe size is 11.8 you can't fake a shoe size of 9.8. Which when you plug 9.8 in for y in the equation above you get the answer of 62.6, which would be the height of the person. While out of the three suspects the smallest height is 64 inches we can conclude that Penelope Paige is the most likely the murderer. I play the flute


 * Lab from 12/1/16**
 * Purpose**: Determining the hydrate Of Copper (II) Sulfate
 * Data:**
 * Compound selected for analysis || copper (II) Sulfate ||
 * Mass of Crucible || 24.25g ||
 * Mass of crucible and dehydrated (wet) sample (g) || 33.01g ||
 * Mass of Crucible and dehydrated (dry) sample -1st weighing (g) || 30.08g ||
 * Mass of hydrated (wet) sample (g) || 8.76g ||
 * Mass of Crucible and dehydrated sample -2nd weighing (g) || 29.82g ||
 * Mass of Crucible and dehydrated sample- if needed ||  ||
 * Mass of dehydrated sample (g) || 5.83g ||
 * mass of evaporated water (g) || 2.93g ||
 * Conclusion:** We found that the hydrate of Copper(II) Sulfate was 5.83g's. we figured this out by; placing a piece of Copper(II) Sulfate in the crucible, finding out the weight of both, evaporating all the water out until it turned white, and weighing the white piece of Copper(II) Sulfate.
