Step 1:I'll solve this problem step by step, following the LaTeX formatting guidelines precisely:
Step 2:: Identify the Given Information
- Mass of titanium = $$104.5 \mathrm{~g}
- Molar mass of titanium = 47.87 \frac{\mathrm{g}}{\mathrm{mol}}
Step 3:: Set Up the Conversion Calculation
\text{Number of moles} = \frac{\text{Given mass}}{\text{Molar mass}}
To find the number of moles, we'll use the relationship between mass and molar mass:
Step 4:: Perform the Calculation
\text{Moles of Ti} = \frac{104.5 \mathrm{~g}}{47.87 \frac{\mathrm{g}}{\mathrm{mol}}}
Step 5:: Calculate the Result
\text{Moles of Ti} = 2.18 \mathrm{~mol}
Final Answer
Key Insights: - Always divide the given mass by the molar mass to convert between mass and moles - Round to appropriate significant figures (in this case, 3 significant figures) - Check that units cancel out correctly in the calculation
