The normality of the acid is 0.20 eq/L.

Explanation:

The equation is

color(white)(mmmmmm)"M(OH)"_2 + "Acid" → "salt + water"
"Amt/meq:"color(white)(mml) 20color(white)(mmmll)20

An equivalent is the amount of acid or base that delivers one mole of "H"^"+" or "OH"^"-" ions.

Thus, 10 mmol of "M(OH)"_2 represents 20 meq of the base.

It reacts with 20 meq of the acid.

"Normality" = "20 meq"/"100 mL" = "0.20 meq/mL" = "0.20 eq/L"
