An SDSU junior has grown a bacteriophage stock during a BIOL 350, General Microbiology, lab. He determines it has a concentration of 3.2 x 1013 phage/mL. He is given a Salmonella typhimurium host culture with a concentration of 6.5 x 1011 cells/mL and adds a 500 uL aliquot of his bacteriophage stock to 3 mL of Salmonella cells. please show work1. What is the m. o.i. in phage/cell? Answer to one decimal place.2. What is the total volume of his phage + host cell mixture? Answer to one decimal place.3. What volume, in microliters, of bacteriophage stock should he add to 3 mL of host cells to have a 0.7 moi?
