Question
**Passage 6:** From the same experiment ($MW_{salt} = 330$), what is the molecular mass of the dibasic acid?
Answer: B
💡 Solution & Explanation
$\text{Salt} = \text{Acid} - 2H + 2Ag$. <br>$330 = MW_{acid} - 2(1) + 2(108)$. <br>$330 = MW_{acid} - 2 + 216 = MW_{acid} + 214$. <br>$MW_{acid} = 330 - 214 = 116 \text{ g/mol}$.
