Answer:
Swimming pool is an example of solution
Explanation:
It has water (solvent) and dissolve ion (solute)
The volume is 12 mL (0.012 L)
Before the aluminum was added, the water reached 132mL. After it was added, it reached 144. That means the Aluminum takes up (144-132)= 12mL of space.
The density = mass/volume. If the aluminum bar has a mass of 78g and volume of 0.012L, 78/0.012=6,500 g/L
Fluorine - 18.998 u
chromium - 51.996 u
tellurium - 127.6 u
dysprosium - 162.5 u
Answer:
.02232 mole
Explanation:
At STP each 22.4 liters is a mole
.5 liters / 22.4 l/mole = .02232 mole
