1. Convert atoms to moles:
* Avogadro's number tells us there are 6.022 x 10^23 atoms in one mole of any substance.
* Divide the number of Ti atoms by Avogadro's number:
(3.50 x 10^24 atoms) / (6.022 x 10^23 atoms/mol) = 5.81 moles of Ti
2. Convert moles to grams:
* The molar mass of titanium (Ti) is 47.87 g/mol.
* Multiply the number of moles by the molar mass:
(5.81 moles) * (47.87 g/mol) = 278 g
Therefore, the mass of 3.50 x 10^24 Ti atoms is approximately 278 grams.
