6. Physical developer is an enhancement method for fingerprints on wet surfaces that works by the deposition of freshly made particles of colloidal silver on to the residues. One of the reagents used is a solution of AgNO3 and the exhibit is pre-treated using a solution of maleic acid (molecular formula CO HA). Calculate the molarity for solutions of (a) 10g of AgNO3 in 50cm of water (b) 2.5g of maleic acid in 100 cm of water. Data: m(Ag) = 107.9 g mol
