To convert the concentrations of the different ions from millimolar (mM) to milligrams per liter (mg/L), we need to consider the molar mass of each ion.

1. Zinc (Zn):
We are given the concentration of zinc as 6.42 × 10^(-2) mM. The molar mass of zinc is approximately 65.38 g/mol.

To convert from mM to mg/L, we can use the following conversion:
1 mM = (molar mass) mg/L

Therefore, the concentration of zinc in mg/L can be calculated as:
(6.42 × 10^(-2) mM) × (65.38 mg/L) = 4.20 mg/L

So, the corresponding concentration of zinc in milligrams per liter is 4.20 mg/L.

2. Copper (Cu):
The concentration of copper is given as 7.16 × 10^(-3) mM. The molar mass of copper is approximately 63.55 g/mol.

To convert from mM to mg/L:
(7.16 × 10^(-3) mM) × (63.55 mg/L) = 0.455 mg/L

Therefore, the corresponding concentration of copper in milligrams per liter is 0.455 mg/L.

3. Lead (Pb):
The concentration of lead is given as 0.965 mM. The molar mass of lead is approximately 207.2 g/mol.

Converting from mM to mg/L:
(0.965 mM) × (207.2 mg/L) = 200.1 mg/L

Therefore, the corresponding concentration of lead in milligrams per liter is 200.1 mg/L.

4. Mercury (Hg):
The concentration of mercury is given as 5.00 × 10^(-2) mM. The molar mass of mercury is approximately 200.59 g/mol.

Converting from mM to mg/L:
(5.00 × 10^(-2) mM) × (200.59 mg/L) = 10.0295 mg/L

Therefore, the corresponding concentration of mercury in milligrams per liter is 10.03 mg/L.

So, the corresponding concentrations in milligrams per liter are:
A. Concentrations of zinc: 4.20 mg/L
B. Concentration of copper: 0.455 mg/L
C. Concentration of lead: 200.1 mg/L
D. Concentration of mercury: 10.03 mg/L
