Always. You never know what kind of chemical you’re dealing with and how powerful it is.
Here is the formula for density:
Density (D) = Mass (M) divided by Volume (V)
So you would do D = 6.147 divided by 9.3
As an as answer you would get: 0.6609677419g/cm^3
Additional information:
The formula for volume is:
V = M divided by D
The formula for Mass is:
M = D times V
I hope this helps :)
I believe it is C, as helium is one of the lightest noble gases making the particles move faster.
The smaller number is the number of protons, and the greater number is the mass.
