The answer gonna be: 1/2^n = 1/2^4 = 0.0625
So, 6.25% sample has not decayed yet!!!
<em>Answer:</em>
The order of liquid from top to bottom is as follow
<em>Explanation:</em>
Chart of densities:
- Red = 1.2 g/cm∧3
- Blue = 1.6 g/cm∧3
- green = 0.8 g/cm∧3
- Purple = 0.1 g/cm∧3
<em>Density: </em>
Density is the ratio of mass and volume as follow
d = m/v
<em>Summary:</em>
- Greater the density, it will be at bottom and vice versa.
- Blue liquid has greater density so it will be at bottom
- Purple liquid has low density, so it will be at top.
It’s Benzene, I do believe :) hope this helped, good luck!
