To find the number of moles of titanium present in the alloy, we can follow these steps:
1. Determine the molar mass of titanium (Ti) from the periodic table. The molar mass of Ti is approximately 47.867 g/mol.
2. Use the given mass of titanium in the alloy, which is 645 g, and divide it by the molar mass of titanium to convert the mass to moles.
3. Calculation: \( \frac{645 \text{ g}}{47.867 \text{ g/mol}} \)
4. Perform the calculation to find the number of moles of titanium in the alloy.
5. After calculating, you will get the number of moles of titanium present in the alloy.
By following these steps, you can determine the number of moles of titanium present in an alloy containing 645 g of titanium.
