Question

2. What is the molar concentration of a solution of LiOH if 65 ml are titrated to an endpoint by 175 ml
of a solution of HBr that is .025 M?

Answer 1

Answer:

0.067 M

Explanation:

LiOH + HBB + H2O

1 mol    1 mol

M(LiOH)*V(LiOH) = M(HBr)*V(HBr)

M(LiOH)*65 mL = 0.025 M*175 mL

M(LiOH) = 0.025 M*175 mL/65 mL = 0.067 M
