The median lethal dose of caffeine is 192 mg per kilogram of body mass. If the average cup of coffee contains 0.0950 g of caffeine, how many cups of coffee would a person weighing 82.0 kg have to drink to overdose? The chemical formula of caffeine is C8H10N4O2 and its molar mass is 194.19 g/mol.

Expert Solution


maximum accepatable dose ofcaffeine of person = 192*82 = 15744 mg

                                   = 15.744 g

average cup of coffee containing caffeine = 0.0950 g

minimum no of cups of coffee have to drink to overdose = 15.744/0.095

                                                       = 165.73

                                                       = 166 cups
