a. The concentration of the acid solution in mol/dm³ is calculated using the formula:
Molarity = (moles of solute / volume of solution)
Molarity = (1.06g / (23 + 12 + 16) g/mol) / (200 cm³ + 20 cm³) dm³
Molarity = 0.0014 mol/dm³
b. The mass concentration of the acid solution is calculated using the formula:
Mass concentration = (mass of solute / volume of solution)
Mass concentration = (1.06g / (200 cm³ + 20 cm³)) g/dm³
Mass concentration = 0.0053 g/dm³
c. The molar concentration of the acid solution is calculated using the formula:
Molar concentration = (moles of solute / volume of solution)
Molar concentration = (1.06g / (23 + 12 + 16) g/mol) / (200 cm³ + 20 cm³) dm³
Molar concentration = 0.0014 mol/dm³
