Lithium hydroxide has a mass of 24 g per mole, so 2.50 g is 0.104 mole.

Dissolve this in 1.50 L, and the concentration is

#[LiOH] = 0.104 mol -: 1.50 L = 0.0694 "mol"/L#

Since LiOH is a strong base, it ionizes completely

#LiOH rarr Li^+ + OH^-#

Since each one mole of LiOH produces one mole of #OH^-#, the concentration of #OH^-# will be #0.0694# mol/L as well.
