Your tyrosinase enzyme assay results in a slope of $0\mathrm{.}001946se{c}^{-1}$ for absorbance at $475nm.$

Give the relative activity of your undiluted crude extract if $30\mathrm{.}00L$ of a $5x$ dilution of the crude extract

was added to a $1\mathrm{.}00mL$ reaction cuvette in performing the assay.

Hint: Look at the data analysis section of the lesson for help in solving this problem.
