    a lysozyme assay was carried out
    an absorbance change at 450nm of 0.047min-1 was recorded when 0.2ml of 1/100 diluted egg white was assayed. how many units of lysozyme are there in o.2ml of undiluted egg? (remember that we defined a unit of lysozyme as the amount of enzyme that causes an absorbance change of 0.1)

    1 unit causes a change of 0.1 absorbance units so 0.47 units will cause a change of 0.047 absorbance units but since your egg white was diluted 1/100 you need to multiply 0.47*100 = 47 units of enzyme.
