Answer:
[Ba(OH)₂] = 0.21 M
Explanation:
Molarity is a sort of concentration for solute that determines the moles of solute contained in 1 L of solution (mol/L).
Solution's volume = 45.6 mL
We convert the volume from mL to L → 45.6 mL . 1 L/1000 mL = 0.0456L
Our solute: Ba(OH)₂
We convert the mass of solute to moles → 1.68 g / 171.33 g/mol =
0.00980 moles
Molarity → mol/L → 0.0980 moles / 0.0456L = 0.21 M
