AI Generated Solution

To solve the question regarding the percentage weight loss when gypsum is totally dehydrated, we can follow these steps: ### Step 1: Identify the chemical formula of gypsum Gypsum is chemically represented as \( \text{CaSO}_4 \cdot 2\text{H}_2\text{O} \). This indicates that gypsum consists of calcium sulfate and two molecules of water of hydration. ### Step 2: Calculate the molar mass of gypsum To find the molar mass of gypsum, we need to sum the atomic masses of all the atoms in the formula \( \text{CaSO}_4 \cdot 2\text{H}_2\text{O} \). ...
