ppb

mass of solute (μg) / total mass of solution (Kg)

A) 43,01% B)XH2SO4= 0,122 C) 7,69 m D) 5,827 M

Bonus Example: A dissolution of sulfuric acid that contains 571,6 g of H2SO4 per liter of dissolution, has a density of 1,329 g/cm3. Calculate A) m/m% B) Molar Fraction C) Molality D) Molality

ppm

mass of solute (mg) / total mass of solution (Kg)

M

moles of solute / volume of solution in liters

m

moles of solute / kg of solvent

XX

moles of solute / total moles of solution

m/m %

mass of solute / total mass of solution *100

v/v%

volume of solute / total volume of solution *100
