Answer 1

Answer:

first find volume occupied by one mole of atom it will be 60/10=6cm^3

now one mole contain 6.022×10^23 atoms

so volume of one atom is  

6/(6.022×10^23)

10^-23cm^3(approx)

Answer 2

Answer:

285.73 cm³

Explanation:

We know that $Density=\frac{mass}{volume}$

we have mass and density

mass of Ga = 69.72 × 25 g

                    =  1,743 g

   given density = 6.1 g cm⁻³

      $volume =\frac{1743}{6.1}$cm³

                          = 285.73 cm³
