To find the molarity of BaCl₂, first calculate the molar mass of BaCl₂: barium (Ba) is approximately 137.33 g/mol and chlorine (Cl) is about 35.45 g/mol. Thus, the molar mass of BaCl₂ is 137.33 + 2(35.45) = 208.23 g/mol. Next, convert grams to moles: 416.48 g ÷ 208.23 g/mol ≈ 2.00 moles. Finally, the molarity (M) is calculated by dividing the number of moles by the volume in liters: 2.00 moles ÷ 2 L = 1.00 M.
Need to know the mass of BaCl2 in order to calculate molarity.
Dissolving in water is a physical change.
Barium chloride or BaCl2
A base reract with acids.
Pure water does not have a molarity because it is not a solute dissolved in a solvent. However, under standard conditions, the molarity of pure water is 55.56 mol/L, which corresponds to its concentration of water molecules.
To find the molarity, first calculate the number of moles of BaCl2 by dividing the mass by its molar mass (Ba: 137.33 g/mol, Cl: 35.45 g/mol). Then, divide the number of moles by the volume of water in liters to get the molarity. In this case, the molarity of 416.48 g of BaCl2 dissolved in 2 L of water is approximately 3.02 M.
