Red #40 has an acute oral ld50 of roughly 5000 mg dye/1 kg body weight. this means if you had a mass of 1 kg, ingesting 5000 mg of red #40 will have a 50% of killing you. determine the amount of dye a 70 kg person would need to eat to reach his or her ld50. how many moles of dye would that be? the molar mass of red #40 is 496.42 g/mol. using the calculated concentration of red #40 dye in the sports drink, how many of liters of sports drink would it take to reach this ld50?
