## Q. 5.2

## Step-by-Step

## Verified Solution

Equation 5.3 allows us to calculate the value of k for this method using the data for the standard

k=\frac{S_{stand}}{C_S} = \frac{0.474}{1.75 ppb} = 0.2709 ppb^{-1} (a)

Once k is known, the concentration of Pb^{2+} in the sample of blood can be calculated using equation 5.4

C_A=\frac{S_{samp}}{k} =\frac{0.361}{0.2709 ppb^{-1}} =1.33 ppb
