Please help me solve this!

Answer : The image is attached below.

Explanation :

For :

Molar mass, M = 48 g/mol

Mass, m = 24 g

Moles, n =

Number of particles, N =

For :

Molar mass, M = 17 g/mol

Mass, m = 170 g

Moles, n =

Number of particles, N =

For :

Molar mass, M = 38 g/mol

Mass, m = 38 g

Moles, n =

Number of particles, N =

For :

Molar mass, M = 44 g/mol

Moles, n = 0.10 mol

Mass, m =

Number of particles, N =

For :

Molar mass, M = 46 g/mol

Moles, n = 0.20 mol

Mass, m =

Number of particles, N =

For :

Molar mass, M = 20 g/mol

Number of particles =

Moles, n =

Mass, m =

For :

Molar mass, M = 44 g/mol

Number of particles =

Moles, n =

Mass, m =

For unknown substance:

Number of particles =

Mass, m = 8.5 g

Moles, n =

Molar mass, M =

The substance is .

particle   p is an electron and particle q is a neutron
