Show all work. 1. Prepare a \( 20 \mathrm{~mL} \) of a \( 1 / 100 \) dilution. Specify the volumes of the sample and the diluent? (2 pts) 2. Based on the following dilution scheme and the data, find the viable counts in the unknown broth. ( \( 5 \mathrm{pts} \) ) 3. What is the final dilution when you add \( 2 \mathrm{~mL} \) sample to \( 18 \mathrm{~mL} \) diluent and dilute it further by \( 1 / 20 \) ? (2 prs) 4. Prepare a dilution scheme for a raw milk sample expccted to contain \( 5 \times 10^{5} \) cfu/ml to get countable colony counts. Indicate total dilution and the number of expected colonies on plate. ( \( 6 \mathrm{pts}) \)
