Answer:
2.2 × 10⁻³ mol
Explanation:
Step 1: Calculate the number of equivalents in 0.50 L of blood
The blood calcium level of 8.8 meq/L.
0.50 L Blood × 8.8 meq/L = 4.4 meq = 4.4 × 10⁻³ eq
Step 2: Calculate the number of moles of calcium
Calcium has a charge of 2. Thus, it has 2 equivalents per mole.
4.4 × 10⁻³ eq × 1 mol/2 eq = 2.2 × 10⁻³ mol
