Answer
a. The chloride level in Amanda's blood is 130 mEq/L.
b. This level of chloride is above the normal range.
Work Step by Step
a.
1. Identify the conversion factors.
Molar mass of chloride ion: $35.45 \space g/mole$
$1 \space L = 10 \space dL$
Chloride ion has a charge of -1: 1 mole $Cl^-$ = 1 Eq $Cl^-$
$1 \space Eq = 1000 \space mEq$
2. Convert the concentration to mEq/L:
$$\frac{0.45 \space g}{dL} \times \frac{10 \space dL}{1 \space L} \times \frac{1 \space mole}{35.45 \space g} \times \frac{1 \space Eq}{1 \space mole} \times \frac{1000 \space mEq}{1 \space Eq}= \frac{130 \space mEq}{L} $$
b. According to the Table 9.6, the normal concentration of $Cl^-$ in blood plasma is between 95 and 105 mEq/L. Since 130 mEq/L is greater than 105 mEq/L, this value is above the normal range.
