Question

**Passage 5:** The Law of Equivalents states that equivalents of all reactants and products are equal. $1.6 \text{ g}$ of a metal was dissolved in $100 \text{ mL}$ of $1\text{N } H_2SO_4$. The excess acid required $20 \text{ mL}$ of $1\text{N } NaOH$ for neutralization. What are the milliequivalents (mEq) of acid reacted with the metal?

Answer: A

💡 Solution & Explanation

$\text{Total mEq acid} = 100 \times 1 = 100$. <br>$\text{mEq excess acid} = 20 \times 1 = 20$. <br>$\text{mEq reacted with metal} = 100 - 20 = 80$.
