I guess lemon juice is citric acid (M=192.123g/mol); n=m/M, m is 3 grams, so n=3g/192.123g/mol, n=0.016mol
Concentration is c=n/V, V is 500ml=0.5l, so c=0.016/0.5l is 0.032mol/l

E. histolytica, which mostly infects humans and other primates and causes amoebiasis, is thought to infect between 35 and 50 million individuals globally. It is believed that E. histolytica infections cause more than 55,000 fatalities annually. Prior to the discovery that at least 90% of these illnesses were caused by a second species, E. dispar, it was believed that 10% of the world's population was affected. Although animals like dogs and cats can briefly contract the disease, it is not believed that they significantly contribute to its spread.

Histolysis literally translates to "dissolution and disintegration of biological tissues."
