To determine the mass of the solvent (liquid) recovered in the sample, follow these steps:
1. Identify the masses provided:
- Boat mass: [tex]\(0.720 \, \text{g}\)[/tex]
- Boat + Solution mass: [tex]\(0.898 \, \text{g}\)[/tex]
- Boat + Dry mass: [tex]\(0.798 \, \text{g}\)[/tex]
2. Use the equation:
[tex]\[
\text{Mass Solvent} = (\text{Boat + Solution}) - (\text{Boat + Dry})
\][/tex]
3. Substitute the given values into the equation:
[tex]\[
\text{Mass Solvent} = 0.898 \, \text{g} - 0.798 \, \text{g}
\][/tex]
4. Perform the subtraction:
[tex]\[
\text{Mass Solvent} = 0.100 \, \text{g}
\][/tex]
Thus, the mass of the solvent recovered in the sample is [tex]\(0.100 \, \text{g}\)[/tex].
