The LD50 for sodium cyclamate in mice is 17.0 grams (cyclamate) per kilogram of body weight  ( LD50 is that dose of a substance that would be lethal to 50% of a population).
If a can of diet soda contains 0.085 grams of sodium cyclamate
                                         calculate the number of cans of diet soda that a 154 lb. human would have to drink to ingest  the dose of sodium cyclamate equivalent to the LD50 for mice.
