Answer:
9.0 g/cm³
Explanation:
Density can be computed with the formula:

Where:
D = Density
M = Mass
V = Volume
In your problem we are given:
84 cm³ = volume
760 g = mass
So we just plug in our given into the formula:



The answer would then be:
9.0 g/cm³
Answer:
1000 gram
Explanation:
because mass is constant everywhere
valance electrons that reside in the outermost shell of an atom in the highest energy level. They are important to atoms because the fewer valence electrons that the atom holds, it becomes less stable.
I take honors chemistry I hope this helps.
