For the malonic acid: 15.6 mg / ml x 100 ml = 1560 mg = 1.56 g malonic acid needed
For MnSO4*H2O: 3.38 mg / ml x 100 ml = 338 mg = 0.338 g of MnSO4*H2O needed
For starch: 0.03% w/v = 0.03 g / 100 ml = 0.03 g of starch needed
Volume of water needed = whatever it takes to make the final volume 100 mls (can't be determined from the info provided).
