Barium hydroxide dissolves as follows. ba(oh)2(s) ? ba2+(aq) + 2oh- (aq) how many moles of ba(oh)2 are required to make 1.0 l of solution in which the ohconcentration is 0.050 m?

There are a number of ways to express concentration of a solution. This includes molarity. Molarity is expressed as the number of moles of solute per volume of the solution. We calculate as follows:

0.050 M = 0.050 mol / L solution
Moles Ba(OH)2 = 0.050 mol / L solution (1 L solution ) = 0.050 mol Ba(OH)2
