To find the mass you need to find the weight of a mol of the molecules by adding up the atomic mass.

N =  14.007 g/mol
H = 1.008 g/mol
S = 32.065 g/mol
O = 16 g/mol

2(14.007) + 8(1.008) + 32.065 + 4(16) = 132.143 g/mol

Now you know how much an entire mol weight you multiply it by how much you actually have 

0.00456 * 132.143 = 0.603 g

Mass of (NH4)2SO4  is 0.6025g

Finding the mass of a compound

Using the equation:

Number of moles = Mass /Molar Mass

Given,

0.00456 as Number of moles of (NH4)2SO4

and Molar mass as

N =  14.007 g/mol=2(14.007)

H = 1.008 g/mol= 8(1.008)

S = 32.065 g/mol= 32.065

O = 16 g/mol=           4(16)

(NH4)2SO4 = 132.143 g/mol

Mass of  (NH4)2SO4 = 132.143 g/mol x 0.00456=0.6025g
