DataPreparation of 50μM H_{2}SO_{4}
[math]\displaystyle{ \frac {50 x 10^3 mol} {L} \times \frac {98.07 g} {mol} \times 10mL \times \frac {1L} {1000 mL} \times \frac {1mL} {1.84 g} = 0.0266mL }[/math] 0.0266mL = 26.65μL Preparation of 50μM Fe_{2}(SO_{4})_{3}
[math]\displaystyle{ \frac {278.01 g} {mol} \times \frac {50 x 10^3 mol} {L} \times \frac {1 L} {1000 mL} \times 10mL = 0.138 g }[/math] 0.138 g Fe_{2}(SO_{4})_{3} in 10mL H_{2}O to get 50mM. Dilute to 50μM by using 0.01 mL (10μL) in 9.99mL (9990μL) H_{2}O NotesThis area is for any observations or conclusions that you would like to note.
