Answer:

#2.1"mol "Ba(OH)_2#

Explanation:

Determine the molar mass of the barium hydroxide.

#Ba=(137.327"g")/"mol"#

#O=(16"g")/"mol"#

#H=(1.008"g")/"mol"#

molar mass of #Ba(OH)_2=((137.327+2(16)+2(1.008))"g")/"mol"#

#=(171.343"g")/"mol"#

We know we have #363.8"g"#.

#(363.8"g")/(x" mol")=(171.343"g")/(1"mol")#

Solve to find that there are #2.1"mol "Ba(OH)_2#.
