1 mole = 6.022 * 10^23 formula units.
1.84*10^24 formula units CaCl₂ * (1 mole CaCl₂/6.022*10^23 formula units CaCl₂) = 3.06 moles of CaCl₂.
There are 3.06 moles of CaCl₂.

Answer:
3
Explanation:
For an ideal ramp, M.A/V.R = 1 where M.A = mechanical advantage and V.R = velocity ratio.
Now, V.R = distance moved by effort, d'/distance moved by load, d = d'/d
Now, d' = 3 m and d = 1 m.
So, V.R = d'/d = 3 m/1 m = 3
From M.A/V.R = 1
M.A = V.R = 3
So, the ideal mechanical advantage of the ramp M.A = 3
Very little electric force is required to cause electron flow in conductors. This is due to electrons called "free electrons", which exist in the atoms of conductors. "Free electrons" are electrons that are very weakly bonded to the atom. ... Metals such as copper, silver, and gold are good conductors.
Well, atoms are loosely bound and free to move through the material. Almost all, or just most, atoms will hold on to electrons very tightly and are insulators.
