Question

A 400 mg sample of hair from a young child is digested to 50 ml a 10 ml aliquot 0.4 ppm standard cadmium solution emission reading determine the cadmium content.

a. True
b. False

Answer 1

To determine the cadmium content in the hair sample, we use the given information and perform calculations using the formula Cadmium content (ppm) = (Emission reading × Volume of aliquot × Dilution factor) / Sample weight.

Step-by-step explanation:

In order to determine the cadmium content in the hair sample, we need to use the provided information. First, we have a 400 mg sample of hair. Then, we digest this sample to obtain a 10 ml aliquot. We know that the concentration of the standard cadmium solution is 0.4 ppm. By using the emission reading, we can determine the cadmium content in the hair sample.

To calculate the cadmium content, we can use the formula: Cadmium content (ppm) = (Emission reading × Volume of aliquot × Dilution factor) / Sample weight

Since the sample weight is 400 mg and the aliquot volume is 10 ml, we can substitute these values into the formula to get the cadmium content.

After performing calculations, we can determine the cadmium content in the hair sample. Therefore, the statement is true.
