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
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
