24.08 x 10²³<span> atoms of boron (b) is equal to how many moles of boron?
</span>
24,08×10²³ / 6,02×10²³=4
<span>b. 4 moles</span>
I don't know the answers to the last two, but I think I know the answer to the first one.
Answer:
1. B
Explanation:
1. I believe that the answer is B - hypo means without, so the one that started low and built concentration of the solute was initially (at the beginning) without/had less solute - therefore, it's hypotonic.

Answer:
80 hours. 2,000 ÷ 25 = 80
<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.
