See below.

Explanation:

We already have a balanced chemical equation, so now the only thing we have to do is the stoichiometry:

Step 1: Convert grams of LiOH into moles using its molar mass.

10.0 g LiOH(1molLiOH23.948grams)=0.418 mols LiOH

Step 2: Use the mol ratio of LiOH to LiBr to find how many mols of LiBr will be produced.

0.418 mols LiOH(1molLiBr1molLiOH)=0.418 mols LiBr

Step 3: Convert mols of LiBr to grams using its molar mass.

0.418 mols LiBr(86.845g1molLiBr)=36.3 grams LiBr

Hope this helps!
