Question

A 49.2 g sample of barium hydroxide is dissolved in water and the solution is diluted to give a final volume of 629.84 mL. What is the final molarity of the solution?

Answer 1

.455 M

Step-by-step explanation:

Ba (OH)^2 has mole weight of (from periodic table) = 171.341 gm/mole

49.2 gm / 171.341 gm/mole = .287 mole

.287 M / .62984 L = .455 M
