4. Calculate the amount of DOPA and DOPAchrome in Tube 6, as follows:
 Tube 6 contains 1 mL of 20 mM DOPA
 mmoles of DOPA present = _______________________________
* convert this to µmol of DOPA
 µmoles DOPA present = _______________________________
As1 mole of DOPA gives 1 mole of DOPAchrome,
 µmole DOPAchrome present at end of reaction = _________________
the reading after 30 min in tube 6 =0.772
