To calculate the molarity of sodium in the given solution, we need to know the molar mass of sodium acetate and the number of moles of sodium present in 12.4g of sodium acetate.

1. Calculate the number of moles of sodium acetate:
- Molar mass of sodium acetate (NaC2H3O2) = atomic mass of sodium (22.99 g/mol) + (2 * atomic mass of carbon) + (3 * atomic mass of hydrogen) + (2 * atomic mass of oxygen)
- Molar mass of sodium acetate = 22.99 + 2(12.01) + 3(1.01) + 2(16.00) = 82.03 g/mol

Number of moles of sodium acetate = mass of sodium acetate / molar mass of sodium acetate
= 12.4 g / 82.03 g/mol

2. Calculate the molarity of sodium:
Molarity (M) = number of moles of solute / volume of solution in liters
= (number of moles of sodium acetate / 2) / (100 mL / 1000)

Now, let's calculate the concentration of both sodium and acetate ions in various units:

1. Concentration of sodium ion (Na+) in units of mg/mL, mg/L, and µg/mL:
- Convert moles of sodium to milligrams: number of moles of sodium * molar mass of sodium * 1000
- Milligrams per milliliter (mg/mL) = (milligrams of sodium / volume of solution in milliliters)
- Milligrams per liter (mg/L) = (milligrams of sodium / volume of solution in liters)
- Micrograms per milliliter (µg/mL) = (milligrams of sodium * 1000)

2. Concentration of acetate ion (CH3COO-) in units of mg/mL, mg/L, and µg/mL:
- Convert moles of acetate to milligrams: number of moles of sodium acetate * molar mass of acetate * 1000
- Milligrams per milliliter (mg/mL) = (milligrams of acetate / volume of solution in milliliters)
- Milligrams per liter (mg/L) = (milligrams of acetate / volume of solution in liters)
- Micrograms per milliliter (µg/mL) = (milligrams of acetate * 1000)

Lastly, let's calculate the concentration of both sodium and acetate ions in units of ppm (parts per million) and ppb (parts per billion):

1. Concentration of sodium ion (Na+) in ppm and ppb:
- Parts per million (ppm) = (milligrams of sodium / grams of solution) * 1,000,000
- Parts per billion (ppb) = (milligrams of sodium / grams of solution) * 1,000,000,000

2. Concentration of acetate ion (CH3COO-) in ppm and ppb:
- Parts per million (ppm) = (milligrams of acetate / grams of solution) * 1,000,000
- Parts per billion (ppb) = (milligrams of acetate / grams of solution) * 1,000,000,000

Please provide the exact volume of the solution in grams or liters to complete the calculations for concentration in ppm and ppb.
