You need to know the space group. Each space group specifies how many "objects" it contains. Multiply that by the number of atoms per molecule/formula unit and you're done.

A formula unit of AgCl contains 2 atoms: 1 of silver and 1 of chlorine.
The formula unit is Ag2SO4, which contains two silver atoms, one sulfur atom, and four oxygen atoms for a total of seven atoms.
The atoms are located within the cell membrane.

The smallest living unit is the cell, which is made up of molecules, which in turn is made up of atoms, but neither molecules nor atoms are alive.
In a diamond unit cell, each carbon atom is located at the corners of the unit cell. Since there are eight corners in a unit cell, each shared by 8 adjacent unit cells, the contribution to the total number of carbon atoms is 1/8 of a carbon atom per unit cell. Therefore, there is 1 carbon atom per unit cell.

A FCC or Face Centered cubic unit cell has 4 atoms. It is calculated like this. There are 8 corners of the unit cell and each corner has one atom.But each atom is shared by 8 unit cells. So. total no. of atoms at corners= 1/8 *8=1 atom . Also, there are 6 faces which have one electron in the centre of it. Each such electron is shared between 2 unit cells. This gives the total no. of atoms at the centre of faces of unit cell=1/2 * 6 = 3 atoms. Adding the two, we get four atoms in an unit cell 1+3=4 atoms.
