Objective

Procedure

  1. A stock solution of HAuCl4 was made, with the attempted Molarity of 10mM.
    1. (moles HAuCl4)/.025L H2O = .01M
    2. 2.5*10-4 mol HAuCl4
    3. 2.5*10-4 mol * 339.785mol/g HAuCl4 = .0849g
    4. .0197g of the .0849g stuck to the weigh paper, leaving .0656gHAuCl4.
    5. .0656g HAuCl4 * (1molHAuCl4/339.79g/molHAuCl4)= xM HAuCl4
    6. .007721M HAuCl4
    7. .0849g HAuCl4 was put in 25mL to make a 10mM solution
  2. A 15μM stock solution of BSA was made
    1. (moles BSA)/.025L = .000015
    2. 3.75*10^-7mol BSA
    3. 3.75*10^-7mol BSA * 66,463g/mol BSA = .0249g BSA
    4. .0249g BSA was put in 25mL to make a 15μM solution
