The concentration of LiOH in the reaction is 0.103 M

<h3>What is the concentration of lithium hydroxide?</h3>

This is a neutralization reaction and the equation of the reaction is written as; H2SO4(aq) + 2LiOH(aq) ---->Li2SO4(aq) + H2O(l)

The average volume of acid used is obtained from;

8.54 + 8.51 + 8.68/ 3 = 8.58 mL

CA = 0.150 M

VA = 8.58 mL

CB = ?

VB= 25.0 mL

NA = 1

NB = 2

CAVA/CBVB = NA/NB

CAVANB = CBVBNA

CB = CAVANB/VBNA

CB = 0.150 * 8.58 * 2/25.0 * 1

CB = 0.103 M

The concentration of LiOH in the reaction is 0.103 M
