LiOH + KCI → LiCl + KOH
a) I began this reaction with 20.0 grams of LiOH. What is my theoretical yield of LiCI?

35.42g

Explanation:

LiOH + KCI → LiCl + KOH

Let us determine the molar mass of LiOH and LiCl. This is illustrated below:

Molar Mass of LiOH = 7 + 16 + 1 = 24g/mol

Molar Mass of LiCl = 7 + 35.5 = 42.5g/mol.

Now, we can obtain the theoretical yield of LiCl as follow:

From the equation above,

24g of LiOH reacted to produce 42.5g of LiCl.

Therefore, 20g of LiOH will react to produce = (20 x 42.5)/24 = 35.42g of LiCl.

From the above calculations, the theoretical yield of LiCl is 35.42g
