27. the density of nickel is 8.91 g/cm3. how large a cube, in cm3, would contain 2.00 x 10^24 atoms of nickel? use dimensional analysis to solve and show all work including units on every number! (5 points)

Answer : The volume of the cube is,

Solution : Given,

Density of nickel =

Number of nickel atoms =

Molar mass of nickel = 58.7 g/mole

First we have to calculate the moles of nickel.

As, atoms form 1 mole of nickel

So, atoms form moles of nickel

The moles of nickel = 3.321 moles

Now we have to calculate the mass of nickel.

The mass of nickel = 194.94 g

Now we have to calculate the volume of nickel.

Therefore, the volume of the cube is,

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
