Calculate the amount of blue dye ingested in an average serving size of 0.8g in 8 f oz of powdered drink. 3. The Lethal dose (LD50) is the amount of an ingested substance that will kil 50 percent o the test sample. It is usually expressed in mg of substance per kg of body weight (mg/lkg) FD&C; Blue Dye #1 has an LD50 of 300 mg/kg. Determine the mass of blue dye that wou be required to reach the LD50 for a 150lb person 150 44 g=6303291:

Explanation / Answer

Blue dye 1

1. Blue dye is well known for its skin damage problems. They cause rashes, color change and could be fatal in some cases. It causes itching, can cause asthma in some cases.

2. Amount of blue dye ingested

since the amount of blue dye estimated to be present in the drink has not been given here, we would assume it to be 2.2 x 10^-6 M

[pl. note, the value for the amount of blue dye in the dring is calculated from experiment you have done in lab. This value needs to be entered to get the correct value of the ingestion]

molar mass of blue dye = 792.84 g/mol

mg of blue dye present in 8 fl oz (236.6 ml) = 2.2 x 10^-6 M x 0.2366 L x 792.84 g/mol x 10^3 = 0.41 mg

So the amount of blue dye ingested in an average would be 0.41 mg
