The new concentrations of HClO and NaClO are  0.25M and 19M

Calculation of number of moles of each component,

Molarity of HClO = number of moles/volume in lit =  0. 500 M

Number of moles = molarity  of HClO× volume in lit = 0. 500 M× 0.025 L

Number of moles of HClO = 0.0125 mole

Molarity of NaClO  = number of moles/volume in lit =  0. 38 M

Number of moles = molarity of NaClO × volume in lit = 0. 38 M× 0.025 L

Number of moles of  NaClO  = 0.95 mole

Calculation of new concentration at volume 50 ml ( 0.05L)

Molarity of HClO = number of moles/volume in lit = 0.0125 mole/0.05L

Molarity of HClO = 0.25M

Molarity of NaClO  = number of moles/volume in lit = 0.95mole/0.05L

Molarity of NaClO  = 19 M

inysia [295]
First, we calculate the mass of the sample:

mass = density x volume
mass = 8.48 x 112.5
mass = 954 grams

Now, we will calculate the mass of each component using its percentage mass, then divide it by its atomic mass to find the moles and finally multiply the number of moles by the number of particles in a mole, that is, 6.02 x 10²³.

Zinc mass = 0.37 x 954
Zinc mass = 352.98 g
Zinc moles = 352.98 / 65
Zinc moles = 5.43
Zinc atoms = 5.43 x 6.02 x 10²³
Zinc atoms = 3.27 x 10²⁴

Copper mass = 0.63 x 954
Copper mass = 601.02 g
Copper moles = 601.02 / 64
Copper moles = 9.39
Copper atoms = 9.39 x 6.02 x 10²³
Copper atoms = 5.56 x 10²⁴

motikmotik
(doesn't really matter that it's zinc :) )
It is 0.75*N_A, where N_A=6.023*10^{23} (in some books 6.022).
