Objective
DescriptionFour 10mM stock salt solutions were made
1 mM·(1/1000) = 0.01 M · 0.1 L = 0.001 mol = 1 x 10-4 mol Fe2(SO4)3 → 1 x 10-4 mol · 562.00 g/mol = 0.0562 g Al2(SO4)3 → 1 x 10-4 mol · 654.6 g/mol = 0.06546 g CuSO4 → 1 x 10-4 mol · 249.68 g/mol = 0.0249 g Na2SO4 → 1 x 10-4 mol · 142.04 g/mol = 0.14202 g
1:100 = 990 μL salt + 10 μL porphyrin 1:10 = 900 μL salt + 100 μL porphyrin 1:1 = 500 μL salt + 500 μL porphyrin Data
